------------------------------------------------------------
Thanks for the reply [~nick].
Tried what you suggested, looks like we only have ASM 7.1 in our classpath
because tika-parsers 1.21 requires that.
I debugged a bit more and looks like an issue with
[https://github.com/apache/tika/blob/master/tika-parsers/src/main/java/org/apache/tika/parser/asm/XHTMLClassVisitor.java].
This class is initialized with OpCode ASM5.
The exception is happening here:
[https://github.com/consulo/objectweb-asm/blob/master/asm/src/main/java/org/objectweb/asm/ClassVisitor.java#L150,|https://github.com/consulo/objectweb-asm/blob/master/asm/src/main/java/org/objectweb/asm/ClassVisitor.java#L150]
so somewhere feature of ASM7 is being used – which is not unexpected since
tika-parsers depends on ASM 7.1.
Does this make sense or am I missing something ?

> XHTMLClassVisitor and tika-parsers pom.
