Re: [jetty-users] Bug between 9.2.3 and 9.2.5

[Jan Bartel <janb@xxxxxxxxxxx>]

Hi Ben,

Sounds like a bug that has been fixed for 9.2.6 (which is just about
to come out). Here's at least one reference to a bugzilla report that
seems like it is the bug you're experiencing:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=454452

And here's the bug that was the root cause:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=452246

regards
Jan
