Linux-Bug with ?
If anyone got my earlier messages to this topic
please excuse. But I never got the mails back and
they did not show up in the archive so I assume
something went wrong.
Hello !
I think there is a Bug in the implementation of the conditional
(ternary) operator in the latest jdk1.2 for linux.
Given the following code:
class test{
public static void main(String[] args) {
int x=6;
double d=7.7;
if (x>d) System.out.println("true");
else System.out.println("false");
System.out.println( (x>d)?99.9:9);
}
}
the correct output is:
false
9.0
as tested with jdk1.2.2 for win32; jdk1.1.7 for linux
jdk1.2-v2 (glibc2.0.7) gives me:
false
99.9
(tested on SuSe-Linux 6.1 )
Could someone please confirm this ?
Oktay Akbal.

That means the segfault on SuSe6.4 is not just the glibc-Version. I claim to remember that both are using 2.1.3. Strange.

Re: J2SEE 1.3 for Linux!
I played again with Suse6.4: java -classic works (of course then without hotspot). It seems that the VM dies after reading (or trying to read) .hotspotrc. Creating an empty File makes no difference. But I can't imagine what this file should contain. Anything (for example blabla) entered there produces: java Unrecognized VM option 'blabla' Could not create the Java virtual machine.

J2SEE 1.3 works on Suse6.4
After much testing with the new J2See1.3 from Sun under Suse6.4 I finally made it working. The surprising Workaround is not to use the Suse-Kernel but a plain Kernel (maybe from 6.4 but without Suse-modifications). Maybe someone likes to make a diff between the Suse-Version and the plain Version. I assume there is some mmap-Problem. (strace on redhat reads something about old_mmap).

Window Manager ?
Hello Everyone. Are there known Problems with running of of the latest jdks (blackdown, sun, ibm) under X11 but without a Windowmanager ? The application uses only one "Window". Thanks.

j2sdk-1.3.0-Sparc Problems!
Hello Everyone, are there any Processor-Requirements with this Version of j2sdk for Sparc-Linux? We made a short try on an old Ultra 2 and did not get any Standard-Demo to work. Mostly we got ArrayIndexOutBounds-Exceptions. Is this a Problem with the old Ultra2 or does our Distribution (Suse7.1 on Sparc with Kernel 2.2.x glibc2.2) not meet the requirements ?

Re: "java.lang.InternalError: Unsupported 16-bit depth"
As a simple guess I would say that the RH-Box uses 16-Bit Color which the JRE on the hp and aix not supports. Try setting the Linux-Box to more Colors.

We have one Application running on TouchScreen with Xfree86 without WindowManager. The application was started directly with xinit. In your case you could use JRE1.3 from IBM which is smaller than JRE from sun. But this might be, because sun has additional classes in their JRE. -- Oktay Akbal -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

weird xinerama problem
Hello! We made an Application that runs with sun j2sdk1.4.0 on Suse7.3. The PCs have Matrox G400 Dual-Head-Cards. Our Application mainly consists of several sub-Applications that are lauchned in seperate Threads. Everything works normally. Moving the Applications to the second screen and back is no Problem. One of the Applications launches a JDialog that stays on screen to display some changing Information. As soon this Dialog is moved to a Screen different from the one the Application is running on the whole Application slows down (nearly freezing Screen refresh does take minutes). the java-Process is consuming all cpu-time. When the dialog is moved back to the same screen the application is running on it takes 5-10 seconds and all returns to normal. Someone has an idea ? I will try to make an easy Test-Programm at monday. Could this problem be related to XFree86 (4.1.0) and not to Java? Unfortunatly all Xinerama-PCs I have access to are identically configured.

Hello again. I just tested our application with the beta2 of j2sdk-1.4.0 and the application ran fast. With the final version or beta3 still slow. The release notes gave not hint so far.

For completeness: -Dsun.java2d.pmoffscreen=false can be used as a workaround.

Re: modal dialogs in 1.4
There seem to be several issues with modal JDialogs in 1.4-final. Some (?) of them do not show up in -beta2. We have a Problem with blank Dialogs and hanging Application that does not only show up under KDE. Is it possible for you to test beta2 ?
