    Description

      The error is:

      Caused by: java.lang.IncompatibleClassChangeError: org/parboiled/transform/ParserClassNode
	at org.parboiled.transform.ParserTransformer.extendParserClass(ParserTransformer.java:43)
	at org.parboiled.transform.ParserTransformer.transformParser(ParserTransformer.java:38)
	at org.parboiled.Parboiled.createParser(Parboiled.java:54)
	at org.pegdown.PegDownProcessor.<init>(PegDownProcessor.java:66)
	at org.pegdown.PegDownProcessor.<init>(PegDownProcessor.java:57)
	at org.xwiki.rendering.internal.parser.markdown.MarkdownParser.parse(MarkdownParser.java:75)

      And the problem is that in WEB-INF/lib we have both ASM 4.0 and ASM 3.1 listed.

      Analysis of the problem:

      • Our Markdown parser uses pegdown which uses parboiled which requires ASM 4.0
      • Our Lucene search uses Tika Parsers which uses ASM 3.1
      • ASM 4.0 is not backward compatible with ASM 3.1
      • Tika Parsers uses ASM to parse class files. In term of XWiki features this means the ability to index class files attached to wiki pages
