We know of no actual problems with GJC. When stepping up
the requirements for Jinterface to JDK 1.5 we just chose
a configure test for a new feature in Sun JDK 1.5 that
we started to use, and that is a new iterator syntax.

We test here at OTP with Sun JDK and IBM Java and have not
(yet) made an effort to try GJC, but if it supports the
new iterator syntax perhaps someone should look into
how much rewriting is needed to make Jinterface build
by not using the String(int[], int, int) constructor.

If Jinterface would build and run with GJC we should start
testing it...
