FULL PRODUCT VERSION :

Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

A DESCRIPTION OF THE PROBLEM :
Since upgrading to Java 7, HotSpot sometimes zombies a LOT of my methods and does not recompile them, leading to dramatic performance regression.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

REGRESSION. Last worked in version 6u45

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Unfortunately I can only reproduce this occasionally in production - not even on my staging machines :(
However, I have compilation logs and stack traces from the degraded case under Java 7, as well as the same thing under Java 7 from the normal case, and the same information from Java 6 where the problem doesn't exhibit itself.

REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
Forced to remain on 1.6
