JAD解决MISSING_BLOCK_LABEL心得

Java反编译工具体会收藏 做Java已经有4年多了，Java反编译工具开始是使用小颖，后来使用DJ Java Decompiler（破解版，嘿嘿），后来不能用了，用google一搜，发现大家都开始使用jad+jadclipse了，用了一段时间了，发现真是好用啊。看来要经常跳上井沿goole以下阿，了解一下新动态。 看jad网站说jad的bug和限制： 1.包含有内部类，则jad处理构造函数的参数时会出错； 2.不支持zip和jar包。（注：如果使用Eclipse插件，则很容易得到包中的某个类的反编译代码） 3.当有标签块，嵌套循环中有break/continue,有goto语句的时候，会提示信息“Couldn't fully decompile method <name>”；当有try-catch-finally语句的时候会提示信息“Couldn't resolve all exception handlers in method <name>” 4. Currently Jad ignores the contents of the Line Number Table Attribute and the Source File Attribute(不明白什么意思) 5.JAD不能处理继承信息，总是把java.lang.Object作为两个不同类的通用父类，需要的时候做强制转换 6.jad对inlined functions处理不好 jad使用过程中发现 SharkUtilities.releaseTransaction(t); break MISSING_BLOCK_LABEL_89; Exception exception; exception; SharkUtilities.releaseTransaction(t); throw exception;这个一般是try-catch-finally语句中的 finally...{ SharkUtilities.releaseTransaction(t); }语句。 类似于 Exception ex; if(!connected) throw new NotConnected("The connection is not established..."); SecurityManager sm = SharkEngineManager.getInstance().getSecurityManager(); if(sm != null) try ...{ sm.check_executionadministration_get_sequence_processmgr(t, userId); } // Misplaced declaration of an exception variable catch(Exception ex) ...{ throw new BaseException(ex); } return SharkEngineManager.getInstance().getObjectFactory().createProcessMgrIteratorWrapper(t, userId).get_next_n_sequence(t, max_number); ex; cus.info("ExecutionAdmin -> Unexpected error while user tries to get the list of process managers"); throw new BaseException(ex);应该是 try...{ if(!connected) throw new NotConnected("The connection is not established..."); SecurityManager sm = SharkEngineManager.getInstance().getSecurityManager(); if(sm != null) try ...{ sm.check_executionadministration_get_sequence_processmgr(t, userId); } // Misplaced declaration of an exception variable catch(Exception ex) ...{ throw new BaseException(ex); } return SharkEngineManager.getInstance().getObjectFactory().createProcessMgrIteratorWrapper(t, userId).get_next_n_sequence(t, max_number); }catch(Exception ex)...{ cus.info("ExecutionAdmin -> Unexpected error while user tries to get the list of process managers"); throw new BaseException(ex); }嵌套try-catch 本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/lkj107/archive/2008/05/26/2484191.aspx
