Tokenizing java exceptions fails if the exception is terminated with a full-stop.

The String "throws java.lang.NullPointerException" is tokenised into the following tokens:

• throw
• java.lang.NullPointerException
• java
• lang
• NullPointerException

... and "throws java.lang.NullPointerException." should do the same thing.
However, the Lucene analyzer does not do this.
