Daniel,
This is a different problem than getting the null method.  Here we are 
expecting "invoke return entry points" in the output of findpc command but 
getting ""method entry point".
The null method problem seems to be specific to AArch64 system and I am looking 
at it separately.

Thanks,
Sharath

fails to find expected output

This test actually fails for me for the same reason that ClhsdbJstack.java 
fails, there is a frame in the stack of the main method that is returning null 
for the method. See the OpenJDK bug at 
https://bugs.openjdk.java.net/browse/JDK-8196969 for details of that issue. 

In this case I get the same problem, that a Method is null in the stack, which 
then causes a failure at 73 of ClhsdbFindPC.java.

Yep sorry - missed that bit.
