Problems with SableVM 1.1.6 and IzPack installer generator

Hello there,

I get the following error when I try to run any IzPack-based installer:

WARNING: could not properly read security provider files:
       file:///opt/sablevm-linux-1.1.6/lib/security/SableVM.security
       file:///opt/sablevm-linux-1.1.6/lib/security/classpath.security
       Falling back to standard GNU security provider wrapper

Any help will be greatly appreciated.

I have attached the output with verbose gc, jni, class loading, etc., in
case it would help in determining where the problem is with this. Let
me know if I should try building with different configure parameters,
or if this is fixed in staging or bugfree SVN branch.

Thanks!
