[undertow-dev] StackOverflowError on AbstractFramedChannel

[electrotype]

Hi,

Using Undertow 1.3.23.Final, I /sometimes/ get this error, when running my WebSocket tests :

part is repeated a lot of times before a stack overflow is reached.

I'm currently not able to reproduce the error on demand, most of the time it works just fine. I'm 
still investigating.

I'd like to know if someone has already seen this? Any potential causes you may think of?

Thanks,

Julien
