Intellij IDEA code coverage incorrectly shows less than 100%

I have a package with five classes. Each class has 100% code coverage, 100% line coverage bar one (which has 98% line coverage). As a result the package code coverage is 88% and line coverage i开发者_JAVA百科s 171%. It doesn't really make sense to me (especially the 171% line coverage) and I was wondering if anyone had encountered this before?

It's a known issue, try IDEA 11 EAP version.
