Hi Weiqi,
We encountered this a while ago, it's Tomcat 7 specific, and actually
reveals a bug that has been in Pebble for a long time:
http://open.jira.com/browse/PEBBLE-71
I haven't had a chance to fix it yet because I'm pretty busy, but I will
get to it, because it seems Tomcat 7 is getting more stable/popular.
Cheers,
James
