Hi,
I have an idea which involves going somewhat deep into the bowls of the
Java Jar class loader when using the official Oracle JDK 6 (and soon 7).
To verify this I started looking at the JDK source code but it's not small
and I'd like to
Ahoy maties!
The time has come for me to upgrade some of my antique hardware, and I
have ordered myself a nice mega-monitor with the ass-whooping resolution
of 2550X1440. This means the old VGA on board won't do and I need to
look at higher-end stuff (DVI-D at minimum). I googled this issue quite

Hi Amos,
I did something like this with the JarSigner code in order to reverse
engineer it in C, which in the end I was able to do. IMHO, gdb is too high
a granularity to get anything usable out of the JVM execution. I suspect
that there is no alternative to sowing System.out.print's
Thanks to both of you.
To give more details of what I'm after - I want to know whether the class
bytecode address points into the mmap(2)'ed jar file or into malloc(3)'ed
memory. I think I found part of the code path inside the jdk source which
does this and now I'm trying to determine what are
Hi Amos,
Pardon me, what does the class loader have to do with JMX?

LWN.net mentions here - http://lwn.net/Articles/518936/ - that the New York

published a feature against software patents:

It also gives one especially damning quote:

Why do you need the Java source for that? Can't you use gdb, find out the
the address of the mmap'ed area, and add a watchpoint there (scripted to
log access and continue).

I don't have experience with ATI but they should work. I don't know how
the drivers are.
NVIDIA works great for me, but I use the propriety drivers, not nouveau

under windows works on ATI, NVIDIA and ivy bridge Intel GPUs

I'd expect to need the source code to make sense from the gdb output, and
maybe also to get the debug symbols.
I thunk I already found at least part of the code path in the source, why
shouldn't I take advantage of this info?
What I wanted to know in my original question is whether anyone in
