Some of the JNI method calls in glass -- at least for the Mac platform -- are make without checking for pending exceptions. This leads to warnings when running JavaFX applications.

If you run any JavaFX application with -Xcheck:jni you will see several warnings of the following form:

WARNING in native method: JNI call made without checking exceptions when required to from CallVoidMethod

We should fix up the Mac glass code and check the other platforms.

See JDK-8306030 for more information.
