Subject Re: Building With OpenJDK 1.7.0
Date Sun, 19 Oct 2008 21:26:19 GMT
yes, that is a known issue due to commons-dbcp uses a delegate pattern 
to implement the java.sql.Connection interface.

a proposed solution for later version of tomcat has been put into bugzilla
https://issues.apache.org/bugzilla/show_bug.cgi?id=46038

for now, you would have to comment out the tomcat-dbcp build out of the 
build script
