Java Weekly 14/15: log4j memory leaks, JBatch monitoring and more...

The Java world is evolving at a rapid pace and it can be challenging to keep track of it. Fortunately lots of great resources are created every week, explaining new features or looking at existing stuff from a different angle.

I am using the Java Weekly series to collect the most interesting links I found during the last week and present them to you all in one place. I hope you find it useful and that it makes it easier for you to keep up-to-date. If you like to suggest a resource or something I can improve on, please leave me a comment.

My Trip to JavaLand 2015

Last week, I attended the JavaLand 2015 conference in Brühl, Germany. If you follow me on twitter, you have probably seen me tweeting about it. And what shall I say, it was a great conference! Well organized, lots of interesting sessions, great discussions and everything happening in a theme park. Yes, that's right: it took place in the Phantasialand theme park!

And did I already mention that I hosted a Java quiz as one of the community activities? :-D

How to activate Hibernate Statistics to analyze performance issues

Did you ever ask yourself why a server request took ages on the production system while your local test system was just fine?
Well, we all had these situations and we will have several more of them in the future. In my experience, strange performance drops are often related to slow database queries. But which query causes the problem? And how to find it, if you can't or don't want to activate logging on your database?

The good news is, there is an easy way to do it. Hibernate can be configured to collect statistics and to provide the required information to analyze the database queries. So lets see what we need to do.
