> The benchmark javac of Spec98 is executed by Harmony, using parameter -XX:gc.minor_algorithm=MINOR_GEN_FORWARD_POOL,
heap size is 32MB, 64MB and more, the Harmony will be crashed.  But in 16MB heap size, Harmony
will execute javac successfully. Executing result looks like following:
> [paul@cse-server Harmony]$ $HA_PATH_V5/java -verbose:gc -Xmx64m -XX:gc.minor_algorithm=MINOR_GEN_FORWARD_POOL
-XX:gc.adaptive=0 -classpath ~/TestGC/Harmony/ spec/benchmarks/_213_javac/Main
> Javac benchmark starting...
> The GC did not provide gc_add_weak_root_set_entry()
> java: /home/paul/Harmony_V5_M2/drlvm/vm/gc_gen/src/mark_compact/../common/gc_for_class.h:192:Partial_Reveal_VTable*
obj_get_vt(Partial_Reveal_Object*): 断言"obj && obj->vt_raw"失败。
> 段错误
