Hi @Hamlin-Li
I am not reviewer, but maybe you could add test for "parallel" in 
BasicJMapTest.java.

That test is for the `jmap` command, not the `GC.class_histogram` jcmd. As I 
pointed out, there are tests in `test/hotpot/jtreg/serviceability/dcmd/gc` that 
already test `GC.class_histogram`. That would be a better starting point.

@plummercj Hi Chris, I have a question which might not be related to the patch, 
my presubmit tests always failed on linux platforms, but I don't think the 
failure is related to my patch. Would you mind to share some point? I totally 
have no idea what's going wrong.
The error messages are as following:

E: Could not configure 'libc6:i386'.
E: Could not perform immediate configuration on 'libgcc-s1:i386'. Please see 
man 5 apt.conf under APT::Immediate-Configure for details. (2)
Error: Process completed with exit code 100.

I believe this has been fixed, so your repo may be missing that changeset at the moment.

David
