 * @test

 * @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?
