RFR <8064470 > JNI exception pending in jdk/src/java/base/unix/native/libjava/FileDescriptor_md.c

[Vyom Tewari]

Hi everyone,

Can you please review my changes for below bug.
Bug:
    JDK-8064470 : JNI exception pending in 
jdk/src/java/base/unix/native/libjava/FileDescriptor_md.c

Webrev:
http://cr.openjdk.java.net/~dfuchs/vyom/8064470/webrev.01/

This change ensure that we immediately return if an exception has been 
raised (result == NULL) by GetMethodId() or proceed to the next
line if there is no JNI pending exception.

if result is NULL, there is a pending exception, and we return. if 
result is not NULL, there is no pending exception, and we proceed to the 
next line...

Thanks,
Vyom
