JVMTI does not abort on OOM it reports an error, so we definitely do not want a terminating allocator! jvmtiError JvmtiEnv::CreateRawMonitor(const char* name, jrawMonitorID* monitor_ptr) { JvmtiRawMonitor* rmonitor = new JvmtiRawMonitor(name); NULL_CHECK(rmonitor, JVMTI_ERROR_OUT_OF_MEMORY); ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/13498#discussion_r1172159575
