Bug fix: Debug builds fail

[Edward Nevill]

Hi Joseph,

This patch looks good and fixes the debug build, thanks for doing this. Would you like to try pushing it, and see if the problems you were having pushing before persist.

Although it now builds, I get assert failures straight off with just the java command on its own. Is this expected? FYI: The assert failure I get is


# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/work/ed/aarch32/jdk9/hotspot/src/cpu/aarch32/vm/macroAssembler_aarch32.cpp:1712), pid=28250, tid=28251
#  assert(bs->kind() == BarrierSet::CardTableModRef) failed: Wrong barrier set kind

All the best,
Ed.
