java.lang.IllegalAccessError

Reported by Cheong Chung Onn | October 8th, 2011 @ 08:44 AM

I am getting IllegalAccessError, the cause seems to point to all anonymous inner class. When I replaced the anonymous inner class with a public static class the problem goes away. Also when I create a plain vanilla app with an anonymous inner class and it works. Application is ran in Test mode. However if app is in Prod mode, the IllegalAccessError does not appear even though there is anonymous inner class.

I thought I had the problem only with 1.2.3 but it seems to happen now with 1.2.2. My app was previously running. Any idea? Below is the output of the error message.

    I confirmed the problem is not caused by anonymous class. I have convert the anonymous inner class to a static inner class and it still have problem (see below) however when after it is declared as a public static inner class it worked again.

    Is this caused by some Play's enhanced class thingy?

    IllegalAccessError occured : tried to access class models.rbac.Space$SpaceComparator from class models.rbac.Space

    I found a workaround for this. Set play.bytecodeCache=false in application.conf

    The workaround didn't seems to work. :(

    Any tips on how I could disable the bytecode manipulation?

    I have made the following observations. I made the above class as a top level class with package access modifier and I still encounter the problem - IllegalAccessError. Next I set the logger to trace level and I found the above class is already being compiled before the message "Listening for HTTP on port 9000 (Waiting a first request to start) ...". And when I start continue the app, the class is being being enhanced.

    I forgot to mentioned earlier that the above class is in a separate PluginModule. I managed to trace that ApplicationClassLoader#loadApplicationClass is the method that throws the IllegalAccessError when a new instance of the SpaceComparator is to be created.

    I have recently encountered this problem with Play 1.2.4-RC2 under Ubuntu x64 11.04. Unfortunately, it is not reproducable - restarting play caused the error to go away. My code uses an anonymous inner class that accessed a local method variable, which normally works fine. I am concerned about the reliability of the play framework for use in production environments when there appears to be differences in each execution.

    Java is the famous programming language and pretty close to human language. As a java programmer all time we face such problems with coding and need the solution of problems. Here on essay writing services website, I found pretty helpful material thank for sharing.
