The setValidateXml method was removed from org.apache.jasper.JspC in 7.0.52. However, this breaks the jspc package build in rawhide. Upstream reinstated this method. Please consider upgrading to 7.0.53. https://issues.apache.org/bugzilla/show_bug.cgi?id=56208
7.0.53 requires newest version of ecj https://bugzilla.redhat.com/show_bug.cgi?id=1050927#c3
Please close if 7.0.54 in rawhide fixed the problem.
Closing the bug as the request to update to 7.0.53+ has been fullfilled. Please reopen if you still has problems.
