Unexpected Exception launching through Ant

[John Muhlestein <jm...@i-link.net>]

I am attempting to launch an application using Ant that I just added logging
to and I am getting an unexpected error.

	Buildfile: build.xml

	launchGUI:
	     [java] java.lang.VerifyError: (class:
org/apache/log4j/LogManager, method: <clinit> signature: ()V) Incompatible
argument to function
	     [java] 	at org.apache.log4j.Logger.getLogger(Logger.java:85)
	     [java] 	at
com.ilink.noc.routemanager.gui.MainAppFrame.<clinit>(MainAppFrame.java:28)
	     [java] Exception in thread "main" 

	BUILD SUCCESSFUL
	Total time: 3 seconds

Here is a snippet of the code to instantiate the Logger (which is line 28
from the above error)
    static Logger logger =
Logger.getLogger("com.ilink.noc.routemanager.gui.MainAppFrame");

And the <target> info from my build.xml

  <target name="launchGUI">
    <java classname="com.ilink.noc.routemanager.gui.MainAppFrame"
fork="yes">
      <classpath>
        <pathelement path="${env.CLASSPATH}" />
        <pathelement location="${JavaClasses}" />
        <pathelement location="${JavaLib}/xercelImpl.jar" />
        <pathelement location="${JavaLib}/xmlParserAPIs.jar" />
        <pathelement location="${JavaLib}/oraclejdbc.jar" />
        <pathelement location="${JavaLib}/log4j-1.2.5.jar" />
      </classpath>
    </java>
  </target>


Has anyone encountered this before or have any ideas?

thanks,
John
