Comments on: Beware of transitive dependencies… For they can be old and leaky http://blog.xebia.com/2008/09/15/beware-of-transitive-dependencies-for-they-can-be-old-and-leaky/ Mon, 26 Jul 2010 20:40:47 +0200 http://wordpress.org/?v=2.8.4 hourly 1 By: Pieter vd Meer http://blog.xebia.com/2008/09/15/beware-of-transitive-dependencies-for-they-can-be-old-and-leaky/comment-page-1/#comment-91634 Pieter vd Meer Tue, 28 Apr 2009 09:12:18 +0000 http://blog.xebia.com/?p=746#comment-91634 Hmm, Although i agree that transitive dependencies can be hell sometimes. I don't think maven or the library at stake is to blame here. The problem is in the testing, when doing a load/stress test it should resemble the actual load on the system. Running a test that does the same thing 1M*1M*1M times is not a test. Just something to see if the result is always the same, and trust me as long as you are not doing creative FP calculations it will be the same. The advice is, run your load and stress test to simulate the load the system will actually recieve, change the request data! Pieter Hmm,

That's why we choose for doing a manual dump :-) Regards, Jeroen Hi Markus,

You can just use the option -XX:+HeapDumpOnOutOfMemoryError and a heap dump will created automatically. Regards, Markus Hi,
