java.lang.UnsupportedOperationException: This feature requires ASM7 in Tika 1.21

We are using Tika java library to parse a bunch of documents (various formats). We are seeing the exception below regularly in our logs on certain documents. Any suggestions on how to fix would be really useful. On initial investigation it looks like its a bug with mismatched ASM between XHTMLClassVisitor and tika-parsers pom.
