Plugin2 crashes when running with Kernel VM. I am not able to reproduce this manually. But Ogt three crash logs while running Kernel Automation tests.

Till now I havent got this crash. Is it a regression in b29 ?

Attached the crash logs.

Crash 1 and 2 same reason crashes on JavaScriptReleaseObject .
