NPE on 4.2RC2 Java analysis

Hi,

I'm getting a NullPointerException when analyzing a Java project on 4.2RC2.
It seems to be the same file each time, but it's not clear why it's failing.

It works fine in Sonar 3.7.

It's using Ant task 2.1 on Windows 7, MySql 5.6

I don't want to post the source of the file here, but if someone can look
into it I can send it privately to them. There doesn't appear to be
anything suspicious in the log (with debug turned on).

We use a mixture of PMD, Checkstyle and Sonar rules.

Here's the stack trace:
