[wtp-releng] help needed on build test failures

[karen moore <karen.moore@xxxxxxxxxx>]

JPT has a bunch of test failures in last night's build and I am unsure 
of the cause.  We did release, but I am confused by the exception (see 
below) appearing in the log file that are preventing our xml content 
types from being loaded.  I updated my target workspace to last night's 
build and do not have test failures. Any ideas would be appreciated.

Thanks,
Karen
