/**

 * @bug 8145221
 * @summary After creating an AppCDS archive, run the test with the JFR profiler
 *          enabled, and keep calling a method in the archive in a tight loop.
 *          This is to test the safe handling of trampoline functions by the
 *          profiler.
 * @requires vm.hasJFR & vm.cds
 * @library /test/lib /test/hotspot/jtreg/runtime/cds/appcds
 * @compile test-classes/MyThread.java
 * @compile test-classes/TestWithProfilerHelper.java
 * @run driver TestWithProfiler
