Bug in schematool encountering malformed connection URL

[Tim Holloway <ti...@mousetech.com>]

I was trying to construct a jdbc URL from my so-called memory and
triggered this. I don't know if there are other malformed URLs that can
also set it off.

when missing '//' from hostname in the connection URL:

'-Dopenjpa.ConnectionURL=jdbc:mysql:tamsdb/tamsdb_test'
