JavaOne / memory leaks revisited...

Memory leaks in print
A few months ago, Gregg Sporar together with A. Sundararajan started an article on memory leaks in the magazine Software Test & Performance. While writing that, he stumbled upon my blog and decided to cover the "java.lang.OutOfMemoryError: PermGen space" exception too. I offered to collaborate on the article. The article eventually grew so much it was split in two. Part one was published a month ago. Yesterday, part two was published.
Memory leaks at JavaOne
Edward Chou submitted a proposal for a BOF at JavaOne 2007. He and I will be presenting a BOF on the "java.lang.OutOfMemoryError: PermGen space" exception. I'll try to record the session with my MP3 player and post it on my blog.
In preparation for our presentation, we've been looking at some real-life examples of permgen memory leaks. We took a few memory dumps that came from actual customers in actual production environments. We discovered a few more improvements we could make to jhat: it was already fairly simple to track the leaks with jhat; with these changes it becomes really simple. We were actually quite surprised how simple. More on that in a future entry, either on my blog or on Edward's.
More at JavaOne
Speaking about JavaOne... I have my hands full. Next to the memory leaks BOF, I'm also presenting a BOF on JBI ("How to develop JBI components") and I'll be co-presenting another BOF on "EE and JBI."
