Apache Directory Studio was misbehaving under the latest OpenJDK on Fedora 19. So I decided to do something about it.
Basically “something” consisted of downloaded the newest version (labeled 2.0.0-M8) to see if that worked better. It did. I had been running something older, but once I overwrote it with 2.0.0.v20130628 all is well again (including the apparent squashing of the bug that caused ADS to fail to close prior connections in the same session).
I’d like to post a snipped from the latest Release Notes here, but unfortunately those packaged with the installer are woefully out of date and the project has seen fit not to publish an up to date document anywhere else.
