We've run into a piece of code that refuses to run under GIJ due to
the following check:
Package p = Package.getPackage("java.lang");
if (!p.isCompatibleWith("1.4")) {
// ... refuse to run
}
Tom Tromey says Package#isCompatibleWith is not implemented. (I
haven't looked at the relevant code myself though.)
