HI, all
This bug is filed after this bug
8010992: Remove calls to global ::operator new[] and new
was anti-delta'ed due to testing failure on JVMTI. Now it takes both.
http://cr.openjdk.java.net/~minqi/8012902/webrev/
ObjectMonitor is an class which should not inherit from any class,
but is has subclass in Jvmti, JvmtiRawMonitor. In previous changeset,
ObjectMonitor is created through NEW_C_HEAP_OBJ/ARRAY macros, but
JvmtiRawMonitor was missed. This is why when it is 'new'ed failed on
disabled global operator new in debug mode. To prevent using more
complex form of marco NEW_C_HEAP_OBJ/ARRAY operator new and new[] added
to ObjectMonitor so JvmtiRawMonitor will inherit for them.
HandleMark should be a StackObj but we create the first one in Thread
ctor in heap, so it did not have StackObj as parent. Added oerator new
and new [] to it though in fact it is used as StackObj. Same treatment
for MemRegion too, it is an _ValueObj (in Linux, it did not inherit from
any). Adding operator new and new[] is mainly avoid using macro
involving alloc/dealloc and ctor/dtor complexity.
The make files, vm.make and fastdebug.make changed under BSD is for
one problem which is not clear: jdk code called operator new in hotspot
library. This only happens on Darwin. Exposure of
CATCH_OPERATOR_NEW_USAGE giving an warning when first time global
operator new and new [] called.
Tested with JPRT, vm.quick, jtreg.
Thanks
Yumin
