*
* @summary Test verifies set/get TLS data and verifies it's consistency.
* Test set TLS with thread name which it belongs to and verify this information when getting test.
* -- cbThreadStart
* -- by AgentThread
*
* Test doesn't verify that TLS is not NULL because for some threads TLS is not initialized initially.
* TODO:
* -- verify that TLS is not NULL (not possible to do with jvmti, ThreadStart might be called too late)
* -- add more events where TLS is set *first time*, it is needed to test lazily jvmtThreadState init
* -- set/get TLS from other JavaThreads (not from agent and current thread)
* -- set/get for suspened (blocked?) threads
* -- split test to "sanity" and "stress" version
* -- update properties to run jvmti stress tests non-concurrently?
