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

[Bartz, Klaus]

Hi Yurii,
you know, we do not like the 1.5 VM because there are some
problems at some points.
But the exception you have got should not be. I have tested with
VM 1.4.2_06, 1.5.0_06 and 1.6.0_beta. No exceptions.
May be your IzPack-install-3.9.0.jar is corrupt. To verify open it
with an unzipper like WinZip and look into "info" (with WinZip e.g.
you can choose after selection via context menu the editor to be
used). The last entry in "info" is "uninstaller.jarp".
If you cannot open the jar file or not open "info" or the last
entry isn't there, your copy of the jar file will be corrupt.
Else I do not know in the moment...

Cheers

Klaus
