Description

This method is synchronized, apparently to protect is the iteration through the m_extensions list. We have seen significant blocking in our applications as this lock encompasses the call to URL.openConnection as well.

As this list is rarely changed, a copy-on-write structure would be more appropriate, but at the very least the, only holding the lock during the iteration would be far preferable.
