<AWT Dev> [9] Review request: JDK-8035640 JNU_CHECK_EXCEPTION should support c++ JNI syntax

[Petr Pchelko]

Hello, 

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8035640
The fix is available at:
http://cr.openjdk.java.net/~pchelko/9/8035640/webrev.00/

In AWT code we have quite a lot of C++ sources, but JNU_CHECK_EXCEPTION macros could not be used there, because the JNI syntax is different in C++.
If approved I'll integrate this fix into the client forest, because we need this in client to fix parfait issues.

Thank you,
With best regards. Petr.
