I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.
Inline-Java

Inline::Java hangs
Hi I have been using Inline::Java successfully for some some, however quite recently my Perl script seems unable to communicate with the JVM. I use Inline::Java like this (the debug only for this test):
use Inline ( Java => 'STUDY' ,SHARED_JVM => 1 ,DEBUG => 2 ,CLASSPATH => 'localtokenservices.jar:itsec-dto-common.jar:commons-logging.jar' ,STUDY => ['a.particular.class'] );

I dont actually write any java myself, I use the STUDY option to identify the class I am after. I am running under Solaris 10, perl 5.8.4, JVM 1.5.0_06-b05. This is the DEBUG level 2 output when I try and create a java object, then call a method in it. Note the two line starting with '**' are my own output indicating when im about to create the object, and call the method. Note that the object seem to be created OK, but when I make the method call it just hangs for several minutes until 'Killed' is displayed:

Note that this particular script was working and has been working for some time, and to my knowledge there have been no software changes or anything. To be sure I deleted my _Inline and let inline rebuild it, however it didnt help.
Any help or advice?
Cheers
