I use the latest 1.4 version  in a VMWare virual W2000 environment
running on a 2,6GByte Linux box. The virtual machine is started with
2448 GByte RAM, however, java crashes if I try to allocate more than
approx 1.6GByte for the heap. Is there a limit under windows - using

I've got a version of the Waba VM that only supports class files
format 45.3 [Java 1.1] (and probably below).
I'd like to modify the source so that it supports more recent formats,

I am evaluating Java as a possible fit for a software project. Among
other platforms, it must target PDA's as well. What packages might I
expect in support of such an application? At a minimum, I believe I
need file I/O, graphics, threading, and networking (TCP/IP sockets,

I write software for eye-movement psychology experiments that requires < 0.1
ms time resolution (we have to be able to draw things to the screen at
precise times, know exactly when they were drawn, etc.).  At present I have

We have an application with, say, 2560 megs of heap space used.
Currently running 1.4.2 w/hotspot using the concurrent GC for the
tenured generation.  128 meg eden, no survivor spaces.  We are not using
the parallel eden collector, since we are running on boxes with 2 proc

received the Install on Demand dialog telling me that I don't have the

now, I wanna do some post-processing of class file, actually, I need
to add some code to the existed class file. my idea is to use djava to
form the byte-code in jasmin version, then I modify the jasmin code to
create new class. but It has many errors after using jasmin to create

Since I'm doing an optimization project for a language, which compiles
to the JVM, I like to know, if there is an easy way to measure the gain
of my optimizations, a.k. compare the two compilation with and w/o
optimizations. How is this done. I don't simply want to measure time ...

JVM structure CONSTANT_Float_info keeps float value

according to JVM spec
Thanks a lot

Suppose I have the following byte code:
public Simple0$();
