Some tests use DbUnit, which has an astronomic number of debug logs. I ran YourKit profiler on that and this ByteArrayOutputStream grew to 1G at one point around which it caused the heap space memory error.
One thing I also noticed when looking at the profiler was that the number of LoggingEvent instances increased dramatically as well before they were eventually garbage collected. Maybe that is just a normal thing though.
Ideally, you would contact the Ant user list to report this problem. The DBUnit folks should be notified as well. (Generating 1GB of logs may not be reasonable.)
I will do that.
I am sorry about the time you spent/wasted on this issue. Thank you for sharing the results of your investigation on this list.
I did not spend that much time. Did that in between a few things. The worst is getting to remember how to use and interpret YourKit. This is not something I do every day so I forget. -- View this message in context: http://www.nabble.com/slf4-with-logback-causes-java.lang.OutOfMemoryError%3A...
