Description

« Hide

This is actually the same as ~~LUCENE-463~~ but I cannot find a way to re-open that issue. I'm attaching a test case by dragon-fly999 at hotmail com that shows the problem and a patch that seems to fix it.

The problem is that a long (as used for dates) cannot be parsed as an integer, and the next step is then to parse it as a float, which works but which is not correct. With the patch the following parsers are used in this order: int, long, float.
