 * @summary converted from VM Testbase nsk/jvmti/ThreadStart/threadstart002.
 * VM Testbase keywords: [quick, jpda, jvmti, onload_only_logic, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *     This is a regression test for the following bug:
 *         4432884 jdbx does not work with jdk 1.3.1 starting with
 *                 rc1 build 19 onwards
 *     The test runs a debugger agent in a separate thread that operates
 *     on behalf of other threads, so when it gets a ThreadStart event,
 *     the debugger agent suspends the new thread and then
 *     calls jni_DeleteGlobalRef with a jnienv * for that new thread.
 *     Then the test resumes the new thread and checks the thread
 *     suspend status.
 * COMMENTS
 *     The test reproduces the bug on Solsparc with JDK 1.3.1-b19
 *     with the following output:
 *     java version "1.3.1-rc1"
 *     Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-rc1-b19)
 *     Java HotSpot(TM) Client VM (build 1.3.1-rc1-b19, interpreted mode)
 *     >>> debug agent created
 *     >>> thread 0: Signal Dispatcher
 *     >>> Signal Dispatcher suspended ...
 *     >>> ... resumed
 *     >>> agent: threadStatus=ffffffff, suspendStatus=1
 *     "Signal Dispatcher" did not resume
 *     FATAL ERROR in native method: could not recover
 *     Exit Code: 1
 *     Fixed according to 4668512 bug,
 *     Ported from JVMDI.
 *     Modified due to fix of the RFE
 *     5001769 TEST_RFE: remove usage of deprecated GetThreadStatus function
 *     Fixed according to 6221885 test bug.
 *
