[izpack-devel] RE: Running IzPack with VM 1.5 without SigSegV

[Bartz, Klaus]

Hi all,
just I have checked in my changes for the VM 1.5 problem in trunk.
The class
com.izforge.izpack.util.Librarian
was changed, the new one
com.izforge.izpack.util.LibraryRemover
added.
Should be created without changing build.xml, but I think
a "clean" will be needed.
Now the dlls are removed with a separate process (like
the mimik in the uninstaller) if the VM has version 1.5
or higher.
Will be nice if some one can test it.
I have a short panel with which an installation crashes
allways (on my box). Should I send it?

Hope it works now with VM 1.5.
If not, let us fix the problem faster as in the past.

Cheers

Klaus
