Description

I am running ManifoldCF 2.10 patched for issues 1512 and 1517.

I recently upgraded Java to 10.0.2 (for another server on the same machine) and find that when I try to create jobs using the Documentum connector, clicking on (e.g.) the Paths tab will give this error dialog:

HTTP ERROR 500
Problem accessing /mcf-crawler-ui/execute.jsp. Reason:
    Server Error
Caused by:

org.apache.jasper.JasperException: An exception occurred processing JSP page /execute.jsp at line 1542

1539:           {
1540:             threadContext.save("JobObject",job);
1541: %>
1542:             <jsp:forward page="editjob.jsp"/>
1543: <%
1544:           }
1545:           else if (op.equals("Save"))

There's a lot of stack trace (which I'll attach) but it includes some ManifoldCF calls:

If I revert to OpenJDK 1.8.0_171 (the version I upgraded from) the issue is not seen.
