Did you run benchmarks? The initial data is quite alarming: Starting from a window including this commit gson's test run timeouts due to taking too long. Pgoyette's amd64 test run with sources from 2011-02-24 04:20:03 UTC took 1:20h to complete and sources from 2011-02-24 09:20:03 UTC took 1:47h to complete. Also, a few test failures seemed to pop up. -- älä karot toivorikkauttas, kyl rätei ja lumpui piisaa
