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

[J-Pro]

Good day, dear IzPack developers.

I renewed my computer, reinstalled all the soft I had, but have problem with 
IzPack 3.9.0 installation. Version 3.8.1 installs without any problem, but 
3.9.0 gives this error when I run "java -jar IzPack-install-3.9.0.jar":

java.lang.NullPointerException

But if I run it as "java IzPack-install-3.9.0.jar", I get this:

Exception in thread "main" java.lang.NoClassDefFoundError: 
IzPack-install-3/9/0/jar


I can't understand what's the problem. Already reinstalld JRE and JDK from 
Program Files to C:\Java, to have no spaces in the path, defined CLASSPATH 
and JAVA_HOME with "C:\Java\jdk1.5.0_09" - didn't help. I've already opened 
3.9.0 sources in IDEA IDE, compiled, run it and got the same error. The 
place is where the "/info" resource is loaded.

Have no clue why 3.8.1 installs ok, but 3.9.0 fails... Can you help me with 
it please?


I have Windows XP SP2 here, JDK and JRE versions 1.5.



Thank you in advance!
