At this moment, Dummy0 class is redefined using RedefineClasses 35 * function to another Dummy0 class and PopFrame function is called to reenter the method. 36 * To verify logic of merging constant pools with regard to JSR 292, the original class has 37 * a invokedynamic call and the new Dummy0 does not have invokedynamic at all. 38 * The test verifies that when class is redefined in a target method (at that moment, 39 * the call site is linked) and frame is popped, the new target method is executed and 40 * the site is relinked. 41 * 42 * @library /vmTestbase 43 * /test/lib 44 * 45 * @comment build dummy class 46 * @build vm.mlvm.indy.func.jvmti.mergeCP_indy2none_b.INDIFY_Dummy0 47 * 48 * @comment compile newclass to bin/newclass 49 * @run driver nsk.share.ExtraClassesBuilder newclass 50 * @run driver vm.mlvm.share.IndifiedClassesBuilder bin/newclass 51 * 52 * @run driver jdk.test.lib.FileInstaller . . 53 * 54 * @comment build test class and indify classes 55 * @build vm.mlvm.indy.func.jvmti.share.IndyRedefineTest 56 * @run driver vm.mlvm.share.IndifiedClassesBuilder 57 * 58 * @run main/othervm/native 59 * -agentlib:IndyRedefineClass=verbose=~pathToNewByteCode=./bin/newclass 60 * vm.mlvm.indy.func.jvmti.share.IndyRedefineTest 61 * -dummyClassName=vm.mlvm.indy.func.jvmti.mergeCP_indy2none_b.INDIFY_Dummy0 62 */ 63
