Radu Cotescu commented on SLING-8329:
-------------------------------------
It seems that this is how {{org.cyberneko.html.HTMLScanner}} notifies
internally that it has reached the EOF. The exception is then caught and the
state reset. Unfortunately it's not something that we can control. This is the
dependency chain:

And it seems that {{net.sourceforge.nekohtml:nekohtml:jar:1.9.22}} is the
latest version. :(
