 * @summary converted from VM Testbase nsk/jvmti/GetFrameLocation/frameloc001.
 * VM Testbase keywords: [jpda, jvmti, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test exercise JVMTI function GetFrameLocation.
 *     The test debug agent calls the function from the hook
 *     function and native method for the test cases:
 *     - current and other threads;
 *     - currently executing instructions:
 *         1) astore_2 after catching exception (in frameloc01a.meth01)
 *         2) monitorenter (in frameloc01a.run)
 * COMMENTS
 *     Fixed according to the rfe 4388972.
 *     Tested bytecode was relocated to frameloc01a.jasm
 *     adjusting the expected locations.
 *     Fixed according to 4669812 bug.
 *     Ported from JVMDI.
 *
 * @library /test/lib
 * @compile frameloc01a.jasm
 * @run main/othervm/native -agentlib:frameloc01 frameloc01
