Hi,

Please review the following fix,

JBS: https://bugs.openjdk.java.net/browse/JDK-8196968

webrev: http://cr.openjdk.java.net/~arajkumar/8196968/webrev

Root cause:
From the crash log, I could see that WebCore image decoder is trying to call the Java \
method(through JNI) after detaching from main thread. This leads to null JNIEnv \
pointer, which causes the crash.

Proposed Solution:
Add a null check before accessing the JNIEnv pointer.

(Note: I couldn't reproduce the crash in my dev machine)

Thanks,
Arun
