[9] RFR: 8036612 [parfait] JNI exception pending in jdk/src/windows/native/sun/security/mscapi/security.cpp

[Vincent Ryan]

Please review this fix to the native code component of the SunMSCAPI provider.
It now checks whether a Java exception (thrown from JNI) is already pending, 
before continuing.
