Modifiying j2me midlet

问题

I want to change some strings in opensource app ( testing purpose ). So I decompiled my app using jad decompiler.

Original class file http://dl.dropbox.com/u/32657135/YourTube.class

issued command Jad.exe Yourtube.jar.java

Got jad as output http://dl.dropbox.com/u/32657135/YourTube.jad.java

Compiling Code Again with no modification

command in cmd javac Yourtube.jar.java

Error

YourTube.jad.java:57: error: ';' expected
        JVM INSTR monitorenter ;
                 ^
YourTube.jad.java:57: error: not a statement
        JVM INSTR monitorenter ;
                  ^
YourTube.jad.java:59: error: not a statement
        this;
        ^
YourTube.jad.java:66: error: ';' expected
        JVM INSTR monitorenter ;
                 ^
YourTube.jad.java:66: error: not a statement
        JVM INSTR monitorenter ;
                  ^
YourTube.jad.java:68: error: not a statement
        this;
        ^
6 errors

I want to know, why I am getting this error on recompiling. Is there anything wrong I am doing?
