Sometimes when decompiling Java code, the decompiler doesn't manage to decompile it properly and you end up with little bits of bytecode in the output. What are the weaknesses of decompilers? Are there any examples of Java source code that compiles into difficult-to-decompile bytecode? Update: Note that I'm aware that exploiting this ...

We ship a Java application whose memory demand can vary quite a lot depending on the size of the data it is processing. If you don't set the max VM (virtual memory) size, quite often the JVM quits with an GC failure on big data. What we'd like to see, is the JVM requesting more memory, as GC fails to provide enough, until the total a...

The JavaEE API comes with the HttpServletResponseWrapper which, to quote the javadoc, "provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet." Without subclassing, this class just passes all calls through to the wrapped response object. ...
I can't see where I'm going wrong with the code below, its probably something obvious but I'm too blind to see it at this stage. I'm passing a date of "01/01/2009" to an instance of calendar. I then try and set the month to 2 for March and the output I see is formatted: 01/01/2009 cal month: 2 cal.set( Calendar.MONTH, mth ); //mth = ...

Have seen this comment in a method: //I wonder why Sun made input and output streams implement Closeable and left Socket behind It would prevent creation of wrapper anonymous inner class which implements Closeable which delegates its close method to an instance of Socket. ...
The justification that I've seen for shall we say "Bastardizing" the Java bytecodes in Android was performance. (I suspect there is another reason.) However by changing the byte codes haven't they made hardware excelleration technologies such as Jazelle moot, and thus actually degraded the performance available for a Mobile Java platfo...
I am a newbie in GWT, and also to Swing/SWT style interface building. I have worked with HTML for a long time, and I know how to build my UIs in that.

I am working on a project in which, to resolve a versioning issue, I am creating many classes which will never be tested and must not ever be used - they just need to be there to keep the compiler happy. I'd like to make sure they are never used. This morning I had the idea of throwing an exception in a static initialization block: pu...
