ASM(来自ObjectWeb)未正确计算MaxStack,即使已设置ClassWriter(Compute_Max+Compute_Stack)

如果字节码无效,最大堆栈和变量计算可能会产生错误的结果。您可以通过运行生成的代码来验证 CheckClassAdapter .

例如,

  ClassWriter cw = new ClassWriter(ClassWriter.COMPUTE_MAXS);
  // generate code into cw instance...

  PrintWriter pw = new PrintWriter(System.out);
  CheckClassAdapter.verify(new ClassReader(cw.toByteArray()), true, pw);
