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.)

Actually we have Package.isCompatibleWith, what we don't
have is any version setting on java.lang or other built-in
packages.
Strangely the BEA JRE dies on this:
opsy. java t
java.lang.NumberFormatException: Empty version string
at java.lang.Package.isCompatibleWith(Ljava.lang.String;)Z(Unknown Source)
at t.main([Ljava.lang.String;)V(t.java:7)
public class t
{
public static void main(String[] args)
{
Package p = Package.getPackage("java.lang");
System.out.println(p.isCompatibleWith("1.4"));
}
}
