Looking at build.properties.default in the 5.5.27 source, you can see the
following:
commons-dbcp.home=${base.path}/commons-dbcp-1.2.2-src
commons-pool.home=${base.path}/commons-pool-1.4-src
commons-collections.home=${base.path}/commons-collections-3.2

Yes, by modifying the properties and rebuilding Tomcat.

That's not a problem, since the Tomcat versions are renamed to avoid namespace
collisions.

No one seems to be reporting any such problems here.

How do you know that? Your symptoms seem to indicate otherwise.

What do you mean by "locked threads"? Post a stack trace if that would help.
