Hi Dave,

Unfortunately there is no stand alone reproducible test case.  It 
appears that 6713913 and the issue  I brought up here are related.  Out 
of curiosity, I was looking into inflater / deflater code to see what it 
means to get the ' oversubscribed dynamic bit lengths tree'.  According 
to the code, it's due to the jar file being not in the right format when 
the error occurred.  The one thing that's suspicious here is, the jar 
file creation.  Their build uses maven's internal code to create a jar 
file on the fly. (this problem happens consistently on Solaris & mac.. 
with that build.)  If there is a jar file (format) verifier to examine 
each bit of the (created) jar, then that would help nail down this 
problem. Would it also be a problem, if multiple threads accessing 
(reading ) the same jar?  (Or any other jar related flags that could be 
enabled to check the integrity of the jar would be of help here.)

I will add the stack traces  to the same bug report. 

thanks,
Harsha
