SonarCloud reports the potential bug:
 Potential leak of memory pointed to by 'owned_monitors_list'

...in code like this:

jvmtiError
JvmtiEnv::GetOwnedMonitorInfo(JavaThread* java_thread, jint* owned_monitor_count_ptr, jobject** owned_monitors_ptr) {
 ...

  // growable array of jvmti monitors info on the C-heap
  GrowableArray<jvmtiMonitorStackDepthInfo*> *owned_monitors_list =
      new (ResourceObj::C_HEAP, mtServiceability) GrowableArray<jvmtiMonitorStackDepthInfo*>(1, mtServiceability);

  EscapeBarrier eb(true, calling_thread, java_thread);
  if (!eb.deoptimize_objects(MaxJavaStackTraceDepth)) {
    return JVMTI_ERROR_OUT_OF_MEMORY;
  }

There are other instances, all of them near new blocks added by JDK-8227745.
