Description

I want to upgrade Commons Javaflow from ASM 4 to 5 (same problem with 4.1 ) and I get this exception:

java.lang.IllegalStateException: Undefined label used
        at org.objectweb.asm.util.CheckMethodAdapter.visitMaxs(Unknown Source)
        at
org.apache.commons.javaflow.bytecode.transformation.asm.ContinuationMethodAdapter.visitMaxs(ContinuationMethodAdapter.java:313)
        at org.objectweb.asm.tree.MethodNode.accept(Unknown Source)
        at
org.apache.commons.javaflow.bytecode.transformation.asm.ContinuationMethodAnalyzer.visitEnd(ContinuationMethodAnalyzer.java:140)

the code triggering this error is:

    public void visitMaxs(int maxStack, int maxLocals) {
        Label endLabel = new Label();
        mv.visitLabel(endLabel);

        mv.visitLocalVariable("__stackRecorder", "L" + STACK_RECORDER + ";", null, startLabel, endLabel, stackRecorderVar);

        mv.visitMaxs(0, 0);
    }

Any idea how to fix that?
