- at g1RootProcessor.cpp:152, the call to process_string_table_roots()
should be moved to after the process_vm_roots() to (as much as
possible) keep in sync with JDK9 code.

- in G1RootProcessor::process_string_table_roots(), the "if (weak_roots
!= NULL)" is superfluous given the assert above it (and better keeps in
sync with JDK9 code).

Otherwise looks good to me.

Thanks,
  Thomas
