We were doing some load testing and we started getting a NullPointerException
at the stack trace below. We don't get the NPE all the time, so I am guessing
some of these objects got corrupted somehow.
One place the clear() method is called from is the recycle() method in the
Response object from the same package.
Has anyone seen this before? My Internet searches did not reveal any other
reports of this. Is this something that has already been fixed in the course
of other changes?
The version of Tomcat is 9.0.12 and we are using the openSSL underneath all
this.
Thanks,
Mark
