[izpack-users] 3.9.0: java.lang.NullPointerException at Installer.main(Installer.java:62)

[J-Pro]

Good afternoon, Klaus.

The first thing I thought when I saw the exception - that jar-file is 
corupt. That's why I re-downloaded the last IzPack version. The same problem 
still exists.
But still, I've done as you wrote - opened "info" and as last words there is 
now: "..... %$INSTALL_PATH/installinfo/Summary.htmt 0uninstaller.jarp"
So I have correct jar-installer.

The most amazing thing is that version 3.8.1 install works without any 
problem! Even without defined CLASSPATH and JAVA_HOME! Interesting..

Well... ok, if you have no idea what can be here - I'll try to continue 
finding out. Maybe I'll install JDK 1.6.0 beta, considering that you tested 
with it.

I'll write here if I find a solution.


Thank you very much for your time, Klaus.
