Subject Re: Need info on IPv6 support for Tomcat in RHEL and SLES distros

Well.  That depends on what the application does.  An application
which makes no assumptions about the size of an address and does not
inspect or process addresses in any way should not care whether it is
dealing with IPv6.  Things like the RemoteAddrValve should be checked
carefully before depending on them to be unaffected.

(RemoteAddrValve itself shouldn't be a problem, but your patterns
might be, and so might the JVM's treatment of v4 vs. v6 addresses.)

There are also URI manipulation subtleties.

I expect that *most* applications won't care -- the spec. writers seem
to have done a thorough job.  But I wouldn't be surprised to find that
there are applications which will need some fixing for v6.

Have a look at this for starters:

Typically when a software vendor says that a product is "intuitive" he
means the exact opposite.
