getTimeStamp() not found in runnable jar, but is found otherwsie
I've have trouble deploying an application that runs fine within eclipse, but generates the following error when creating a runnable jar (using the option: **extract required libraries into generated JAR**):

    org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NoSuchMethodError: org.apache.log4j.spi.LoggingEvent.getTimeStamp()J)
            at org.eclipse.swt.SWT.error(Unknown Source)
            at org.eclipse.swt.SWT.error(Unknown Source)
            at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Unknown Source)
            at org.eclipse.swt.widgets.Display.runAsyncMessages(Unknown Source)

            at org.eclipse.jface.window.Window.runEventLoop(Window.java:820)

I'm using log4j-1.2.16.jar and it's included in the generated jar. 

I'm not sure where to troubleshoot, I've tried to find other (older) instances of org.apache.log4j.spi.LoggingEvent in other jars that are included, but so far I did not find any.
