Frames not showing up quite correctly?

[Dustin Lang]

Hi,

Before I submit this to jitterbug, I'd like to make sure I'm not just on
crack.

This used to work before I upgraded (to JDK1.1.7, XFree86 3.3.3.1, and
kernel 2.2.0, from JDK1.1.6, XFree86 3.3.2(?), kernel 2.0.36.  Window
manager = fvwm2).  It also works correctly on win32.  I don't have access
to a Solaris machine to check if it happens there.

What happens, at least for me, is the Frame shows up on screen at the
right size, but the body of it is all gray.  If I drag it to a nearby
location, it is drawn correctly.  Also, if I uncomment the last line, it
is drawn correctly.

I'm not sure, but I believe it should be drawn correctly without the
explicit setLocation?

Thanks (and sorry for wasting your time if I am in fact on crack),
dstn.

System.exit(0);
}
});
pack();

show();
// This will make it be drawn correctly.

[Aaron Gaudio]

It is a bug, and it seems to be related to the setResizable() (if
you comment that out, it appears as normal).

  Well then I'm sorry. I never saw it mentioned. I had seen plenty of
people: A> Asking when will it be done or B> Asking for everything you
have so they can do it. I had not ever seen anyone ask for a snippet of
non-proprietary code so that a large base of programmers could help at
least determine if the bug was in linuxthreads or on the VM itself.

 I have always fully realised that and simply made a humorous (to some
of us it seems) comment. Sun has the right to have any license they
want, and I've never thought they were wrong for the one they have
chosen.

 I didn't ask for this either.

 I have read the FAQ and thought my request differed enough from what is
commonly asked. And I never suggested that they should do anylike like
change the license.

 I wasn't asking for just me. I was hoping to get a piece of code that
both demonstrated the problem and was under no license from Sun. In
doing so I:
Thought a huge number of people could take a whack at it.
Thought we could at least nail down where the bug is.
Thought we could fix said bug.
Realized that nailing down the piece of code that exhibits the problem
could be difficult.
Realized that then generating a hunk of code that could be released
that also exhibited this code without stepping on anyone's license would
be even more difficult.
Realized that most of the important people in the project have a filter
on their mail, stating something to the effect of /1.2|Java\s*2/ &&
killkillkill(); :)
Already appreciate the had work that has gone into the project, and am
in no way trying to pressure anyone to hurry up or wonder "One month
from when?"
Didn't expect the Spanish Inquisition.

  In my best Steve Martin impersonation (which isn't really all that
good):
"Well, excuse me."

Rubbish.  They're in MSB in classfiles, but internally, the JVM will
whatever is the platform's way round, otherwise it'll have to
convert everytime it does things like addition (and that would of
course be slow).

On a small-endian machine, the values would only be converted to
big-endian when they're written to a file, or sent out over the network.

Help about doc on source of JDK

[Pierre Bizzotto]

Hi, 
 We have some problem about the mind of the source code of the JDK 1.1.6.

 we are two students at University of Rome in COMPUTER SCIENCE. We have
the source code of JDK of the SUN. 

 We must generate a JVM for a parallel machine. But we have some difficult
to understand how the THread are handled by the O.S.

We are working on Linux  RedHat 5.1 /Suse 6.0 with JDK 1.1.6.

This documentation is very important for us.

Thankyou 

/* this is a segment of source code where we found difficulties !!
   how can threads change context ?  
*/
if (timerIsSet(&timeout)) {
t = timeout;
timerSub(&t, &time);
sysAssert(timerIsSet(&t));
scheduleAlarm(t);
}

I realize this is off-topic and off-list, but I have tried
twice to email Rob Schoening privately and both times the
email bounced. And the fact is I'm rather desparate.

I saw Rob's post regarding Java on the BeOS and it renewed
my hopes. Is there any Java port for the BeOS? I don't care
what version, is there a JVM at all for the BeOS available
and where?

Thank you and of course, please reply privately as this is
not on-topic for the list.

Re: Offering help on 1.2.

[Kelly Campbell]

Can the current diffs be posted somewhere so people who have executed a
non-commercial source license with Sun can try to help with the port?

I see nothing in the Source license I signed (even though it says version
1.1.x at the top, but they sent me 1.2 sources) to keep the
platform-dependent diffs from being posted before the JCK is passed.

thanks,
Kelly

I read your update on the LWN.  I just wanted to say that on behalf of the

enough for us.
 
Your post sounded like you were getting a lot of annoying "when will it be

thanks.
 
So, thanks.

Hi,

How can I read the files of /proc directory with JDK?  The information
of these files is generated with the  cat option.  (EX:  cat
/proc/meminfo).  It information don´t is fixed in these files.

Actually, I was wondering whether the Java Language Spec says anything
about what byte order should prevail. I searched for it but couldn't
find anything about endianness or byte order. Then again, I didn't
read the whole darn lot.

I now have two different opinions. Some say Java is big-endian, some
say it depends which machine it's on. Who's right? Proofs, please.

Robert.

Class files and serialized objects are MSB.  The endianness of the VM
itself is implementation dependent; however, if you could devise a
pure-Java program that could detect the endianness of the VM, you
would have found a bug in the spec.

We eventually determined that this was due to the extended key mappings
which are part of the 3.3.3 XServer.  We can turn these off in our own
X-configuration file; however, not everyone may want to do this.  Are there
any plans for changing the JDK to deal with the new key mappings?  How are
others dealing this this?

Re: How can I do it?

[Chris Abbey]

Do a runtime exec of "cat /proc/meminfo" and attach the process's
stdout to an io reader of some sort (it's only a stream afterall)
@see Ljava/lang/Process, Ljava/lang/Runtime for needed methods.
Just remember that by doing this you have:
1. broken platform independence.
2. created a requirement that your linux users have the /proc
 filesystem installed and configured, and have read authority.

First of all, let's try to take this off this list. I'm
posting again so I can redirect any further correspondence
to a new location.

Thank you for telling me. Look, if there is an effort, let's
get it organized. I'll gladly set up a web site and mailing
list for the effort. If anyone knows if there already is
such a thing, please tell me ([EMAIL PROTECTED]). Otherwise
in two days, if I do not hear that there is already an
organized effort somewhere, I'll put up a site at the
following url to get started:

http://beos.knOcean.com/

Look for it on Thursday (perhaps earlier).

Considering I've done several searches on a couple search
engines and couldn't find anything about it... I don't know
if there is any other website about it.

Also, one more note--Rob, I responded to your private email
(thank you) but it still could not be delivered. What's up
with your email address?

Thanks,
