For this code org.objectweb.asm.util.ASMifierClassVisitor generate next:

mv = cw.visitMethod(0, "g", "(J)V", null, null);
mv.visitCode();
Label l0 = new Label();
Label l1 = new Label();
Label l2 = new Label();
mv.visitTryCatchBlock(l0, l1, l2, "java/lang/InterruptedException");
mv.visitLabel(l0);
mv.visitVarInsn(LLOAD, 1);
mv.visitMethodInsn(INVOKESTATIC, "java/lang/Thread", "sleep", "(J)V");
mv.visitLabel(l1);
Label l3 = new Label();
mv.visitJumpInsn(GOTO, l3);
mv.visitLabel(l2);
mv.visitFrame(Opcodes.F_SAME1, 0, null, 1, new Object[] 
{"java/lang/InterruptedException"});
mv.visitVarInsn(ASTORE, 3);
mv.visitVarInsn(ALOAD, 3);
mv.visitMethodInsn(INVOKEVIRTUAL, "java/lang/InterruptedException", 
"printStackTrace", "()V");
mv.visitLabel(l3);
mv.visitFrame(Opcodes.F_SAME, 0, null, 0, null);
mv.visitInsn(RETURN);
mv.visitMaxs(2, 4);
mv.visitEnd();


This some different from your code
