> The regex validator tries to validate the 'workflow-app name' against the
> pattern 
> <xs:pattern value="([a-zA-Z_]([\-_a-zA-Z0-9])*){1,39})"/>. If the 'name' is very long and doesn't match against the pattern used in schema, it gets stuck for a
> long time and heavily increases the CPU usage.
> Specifically the users saw this when they used a period in their wf name
> This problem is solved in xerces 2.10.
