-----------------------------------

             Summary: prettify fails on 6th declaration
                 Key: JSPWIKI-879
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-879
             Project: JSPWiki
          Issue Type: Bug
          Components: Plugins
    Affects Versions: 2.10.1
         Environment: tomcat 8.0.21, ibm java 8, AIX 6.1 JSPWiki 2.10.1
            Reporter: Nathan Revo
            Priority: Minor


I am upgrading from an older version of JSPWiki and figured we didn't have anything special in our pages so I re-used the existing setup.  When I visit a few of the existing pages with many "prettify" tags the page blows up with the message: "Tag failed
javax.servlet.jsp.JspException: WikiContext may not be NULL - serious internal problem!"  followed by "Error.jsp exception is: 
java.lang.StackOverflowError
        at java.util.regex.Pattern$Branch.match(Pattern.java:4615)
"


if I change the pages to include 5 or less %%pretify the errors go away.  

I can
