    When using the Regular Expression Job Filter a simple expression like publish* entered into the Regular Expression text box does not return any jobs with name starting with 'publish'. This is when using Match Value of 'Job name' and Match Type 'Included Matched'. In fact it only seems to work when you enter the exact name of a job into the Regular Expression. Also get the following error when entering *publish into the Regular Expression texbox: {code} javax.servlet.ServletException: java.lang.RuntimeException: Failed to instantiate class
