RFR: JDK-8210221: missing-field-initializer warnings/errors while building vmTestBase

[Roman Kennke]

Hi there,

JDK-8209611 seems to cause many missing-field-initializer warning-errors
like below:

I am using gcc 4.8.5

Compiling libvmdeath001.cpp (for libvmdeath001.so)
In file included from
/home/rkennke/src/openjdk/shenandoah-jdk/test/hotspot/jtreg/vmTestbase/nsk/share/jvmti/unit/libHeap.cpp:29:0:
/home/rkennke/src/openjdk/shenandoah-jdk/test/hotspot/jtreg/vmTestbase/nsk/share/jvmti/jvmti_FollowRefObjects.cpp:38:44:
error: missing initializer for member
'_jvmtiHeapCallbacks::heap_iteration_callback'
[-Werror=missing-field-initializers]
 jvmtiHeapCallbacks g_wrongHeapCallbacks = {};


There are many more of those in the build log.

I propose to disable this warning for now.
