Numeric Custom Fields with Floating Point values cause exception.

I've just tried upgrading to JIRA 3.2, and am getting an error whenever I try to perform a search.

I've tracked down the problem, it's occouring with custom numeric fields using a floating point value, line 33 of LongFieldStatisticsMapper is attempting to cast the string to a long value, when it should be casting it to a double value.

Maybe it should be renamed NumericFieldStatisticsMapper and return a BigDecimal value rather than a long?

Here's a stack trace:
