I think I figured it out. With the attached test I could reproduce the
problem on IKVM as well. The attach Classpath patch fixing things,
although past 0.20 I think we should refactor the security properties
like I did with the system properties (i.e. introduce a
gnu.classpath.SecurityProperties class).
As you can see in the test, there is still the incorrect
"charsetProvider" permission being checked. I'm looking into that one as
well.
