Kathey Marsden commented on DERBY-3607:
---------------------------------------

One thing to keep in mind is that this is an all volunteer effort, so there is 
no guarantee that someone will look at your issue. That said, this seems a  
serious issue that I and  I am sure others  would like to see fixed.  One thing 
that caused me to back off of looking at the repro was that I had to install 
software on my pc and I wasn't sure what impact that might have.  If I had a 
junk pc to install it on I would, but I don't right now.    Your next step 
might be to try to create a java program based on what your application is 
doing and see if you can reproduce the problem.  That way  you can post the 
java source so that developers can compile it themselves.  Then  you'll  have a 
greater chance of someone taking a look and being able to resolve the issue.
