URL in Email notify missing port information after migration b19 -> b20

Hi All,

we are facing a problem with URLs in issue change notification emails.
After we upgraded an installation from b19 to b20 the URLs do not contain
the http port anymore.

Before:
http://scarab.host.lan:48080/scarab/issues/id/ABC123

After:
http://scarab.host.lan/scarab/issues/id/ABC123

We configured the "scarab.http.port" property at build time to be 48080,
and this value is also present in the current runtime config. After poking
around a bit I found that a database table named SCARAB_GLOBAL_PARAMETER
also holds that value. However, in our current installation the value in
the table is "@SCARAB.HTTP.PORT@". When I manually changed this to 48080
the port wasn't included in the URL either. But I admit that I didn't
restart Scarab nor the Tomcat after I did that change.

Btw. there exists a migration SQL that was created during the build that
wrote the "@SCARAB.HTTP.PORT@" to the table.

Any suggestions on how to get that port back into the URL?

Any help appreciated, regards
Torsten
