I'm running Mac OSX 10.9.5


I installed without problem and it runs fine.


However, when trying to install it hangs at step 6 of the install program. Running the installer from the command line showed that the installer encountered this error:

Exception in thread "IzPack - Unpacker thread" java.lang.ClassCastException: java.base/jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to java.base/

at com.izforge.izpack.installer.unpacker.UnpackerBase.logIntro(

at com.izforge.izpack.installer.unpacker.UnpackerBase.unpack(


at java.base/


Any workaround for this?
