I have a (Java) program that does this, although I added the comments
by hand.
Writing a decompiler seemed like a good way to learn jvm. I didn't
originally intend to decompile byte codes, by as usual I got carried away

I'm pretty sure try{}catch{} catch blocks add NO overhead to code,
unless the exception actually gets thrown. But exceptions are
supposed to be
exceptional, so who cares how slow it is ?
Check out how exception handling is implemented in Java byte-code
in the Java Virtual Machine Specification, 4
The java language specification is a little difficult to follow on final static
fields.
The best place to look is 13.4.8 - Binary Compatability. This says
"We call a field that is static, final, and initialized with a compile-time
constant expression a primitive constant."
and it is impl
This sounds like a HUGE bug !
Is it just in the Blackdown JDK 1.2, or also in Suns JDK ?
Is there a fix ?
Are there others like this ?
Where is a good place to look for such hi-impact bugs ?

You say you get a stack overflow ? is that stack overflow as in
java.lang.StackOverflowError ? That sounds impossible !!
This error is supposed to mean too many nested method calls, but
your program doesn't do any nested calls !
If this is what is happening, send me the class file
and I'll decomp
Depends which Java you have. Its probably Kaffe if you installed from
a redhat RPM. In that case it will be JDK 1.1, and you will need to set
the classpath to point at the class library.
If you can't find any documentation, you could always download
the tools documentation from Suns web site

Hi Crispin, How you doing?
Your original question never did get a satisfactory answer.
However it's definitely not the same as Luigi's.
Perhaps you could try the code below; on Suns Windows JDK1.2
the total
stays constant at 1m, and the free highwater mark hovers
around 820k,
at least for the fi
Fair comment. I was one of those who had a moan about Swing in this
thread, but I still think Java is the best development tool I have ever seen.
I guess we all got used to this luxury already!

Sorry about the syntax error: the options are different in different JDKs;
-Xmx32m is correct for Suns JDK 1.2.

In JDK 1.2 the default max heap size is 16 Mb - I can't remember what
it was in 1.1. Is this your problem ? You can specify a larger heap
with the command line option -Xmx32m, for example.

I'd have to go along with Brad on this, after using the Swing text API.
I ended up having to subclass lots of stuff, while reading the java sources
to find out what the superclasses were up to.

Not only is Visual J++ not Java, the Java VM delivered with
Internet Explorer is not java - MS has removed rmi and Corba.

Hi,
The servlet development kit is not in Suns JDK 2 - you have
to download it
separately. To have java & javac, etc. pick it up, copy
servlet.jar to
jdk/jre/lib/ext/
If you want to use the demo httpserver, also copy the
server.jar to this directory.
See jdk/docs/guide/extensions/index.html for t
My first guess would be that the jit is better at static calls than virtual.
