I am fine with the patch going in into 1.3, assuming there are no other
regressions. But please avoid this for HEAD.

Is it possible to add a reproducer along with the fix?

The error can probably be ignored safely here (though it may break an
application if it really needs the permission). But I am afraid this is
really an indication of a deeper bug in the classloader. This fix may
make this particular application work, but other applications may remain
broken if the circularity error is detected in some other part of code.
I would prefer to fix the root cause, if at all possible, instead.

Thanks,
