RE: sableVM running tomcat

Hello,

I tried the new version of the sablevm and even ran tomcat. When I see
it through the browser, the tomcat's default page shows up.
The following is the log which is displayed during the running of
tomcat:

Hope this information is enough for debugging.

Release 1.11 does contain some important Method.invoke() fixes.  I think
somebody should to try running tomcat with 1.11 (debug version, ideally,
so that we get precise information on errors), and report any problem.
