OutOfMemoryError throws out of JVM won't notify hotspot, so debug.cpp::report_java_out_out_memory won't handle it. More details are in JDK-8257790.

The following flags won't respect OOME from java libraries. We need to make the description more clear to users.

HeapDumpOnOutOfMemoryError -- "Dump heap to file when java.lang.OutOfMemoryError is thrown"
OnOutOfMemoryError -- "Run user-defined commands on first java.lang.OutOfMemoryError"
CrashOnOutOfMemoryError -- "JVM aborts, producing an error log and core/mini dump, on the first occurrence of an out-of-memory error"
ExitOnOutOfMemoryError -- "JVM exits on the first occurrence of an out-of-memory error"
