Hi Stack

JVM version is 1.6.  There was no profiling done.  
In the TreeMap remove method we try to compare and then remove.  So may be
its not able to find the intended key as the map is corrupted and hence the
comparator is stuck and runs infinitely.

Is it for sure stuck there?  Maybe its stuck in comparator comparing?

What version of JVM?  Were you profiling at the time?
