Hi Leslie,

This is likely the same problem as was reported in https://bugs.freebsd.org/225054#c8, and fixed by the following patch:

https://svnweb.freebsd.org/ports/head/java/openjdk8/files/patch-hotspot_src_share_vm_services_memTracker.cpp?view=markup&pathrev=459368

Can you please try that out, and see if it fixes it for you too?

> I started to use and contribute clang static analyzer[2] just for finding the bugs for open source software from LLVM 3.x,  perhaps it is a bug of LLVM 8,  because jdk8u is just able to print out '-version' after compiled with llvm-3.9.1,  I will rebuild the LLVM 8 again,  then rebuild jdk8u for triple check.
