FULL PRODUCT VERSION :
1.7.0_02

FULL OS VERSION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
When I obfuscate my code a certain portion of it creates an error. I decompiled it and tested out the code by compiling normally and there was the same issue so I know it was not the obfuscators fault.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just execute the method given below.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Should just execute without any errors.
ERROR MESSAGES/STACK TRACES THAT OCCUR :

CUSTOMER SUBMITTED WORKAROUND :
Added printlines inside the loops to see where it stops and it worked.
