This was a simple change. I must have misread the documentation of
Inline::Java as I was using calls like:
Java::JCR::PropertyType::name_from_value()
rather than the correct:
Java::JCR::PropertyType->name_from_value()
I just had to change a couple lines in the package generator script and
regenerate the packages to correct the problem.
This will be part of the next release.
