Building ElasticSearch 0.19.3 - failing unit tests on Windows 7

Hi, I got a copy of 0.19.3 (elasticsearch-elasticsearch-v0.19.3-0-g078c8da.zip from github), and tried to build it using Maven 3.0.3 on Windows 7 Enterprise 64-bit. It ran to completion, but reported 13 tests failed out of 842. Before I try to dig in further - does anyone know whether these SHOULD run OK on Windows 7?

Thanks!

Here are the results of the failed tests:

Tests run: 842, Failures: 13, Errors: 0, Skipped: 0, Time elapsed: 1,706.96 sec <<< FAILURE!
