示例2: createMethodBody
import jdk.internal.org.objectweb.asm.MethodVisitor; //导入方法依赖的package包/类
private static void createMethodBody(MethodVisitor mv) {
Label classExists = new Label();
// Cache resolution errors
createLoadNonExistentClassCode(mv, classExists);
// Redefine our own class and method
mv.visitMethodInsn(INVOKESTATIC, "RedefineRunningMethodsWithResolutionErrors", "redefine", "()V");
// Provoke the same error again to make sure the resolution error cache works
createLoadNonExistentClassCode(mv, classExists);
// Test passed
mv.visitInsn(RETURN);
mv.visitFrame(F_SAME, 0, new Object[0], 0, new Object[0]);
mv.visitLabel(classExists);
createThrowRuntimeExceptionCode(mv, "Loaded class that shouldn't exist (\"NonExistentClass\")");
}
示例3: createLoadNonExistentClassCode
import jdk.internal.org.objectweb.asm.MethodVisitor; //导入方法依赖的package包/类
private static void createLoadNonExistentClassCode(MethodVisitor mv, Label classExists) {
Label tryLoadBegin = new Label();
Label tryLoadEnd = new Label();
Label catchLoadBlock = new Label();
mv.visitTryCatchBlock(tryLoadBegin, tryLoadEnd, catchLoadBlock, "java/lang/NoClassDefFoundError");
// Try to load a class that does not exist to provoke resolution errors
mv.visitLabel(tryLoadBegin);
mv.visitMethodInsn(INVOKESTATIC, "NonExistentClass", "nonExistentMethod", "()V");
mv.visitLabel(tryLoadEnd);
// No NoClassDefFoundError means NonExistentClass existed, which shouldn't happen
mv.visitJumpInsn(GOTO, classExists);
mv.visitFrame(F_SAME1, 0, new Object[0], 1, new Object[] { "java/lang/NoClassDefFoundError" });
mv.visitLabel(catchLoadBlock);
// Ignore the expected NoClassDefFoundError
