> This is fixing the JVM TI GetThreadState issue which returns for terminated virtual thread state = 0 instead of 2 (`JVMTI_THREAD_STATE_TERMINATED`). The problem was in the function `JvmtiEnvBase::get_threadOop_and_JavaThread` which does a check and reurns JVMTI_ERROR_THREAD_NOT_ALIVE a little bit early (before the values of `java_thread` and `thread_oop` are set). This was a root cause of the `GetThreadState` incorrect behavior.
