Hi David,

I'm pleased to discover I am not alone! You forgot to reply to the 
mailing list, so I will do it now.

FYI I am running the new snapshot under:

java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK Client VM (build 23.7-b01, mixed mode, sharing)

and

Apache Tomcat 7.0.42 (I haven't tried it with tomcat trunk yet).

Regards,

Brian
