[Bug 66600] New: NPE in certain scenarios

https://bz.apache.org/bugzilla/show_bug.cgi?id=66600

            Bug ID: 66600
           Summary: NPE in certain scenarios
           Product: Tomcat 9
           Version: 9.0.75
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: boris_petrov@live.com
  Target Milestone: -----

I'm not exactly sure when. I think it happens when some requests that take a
very long time in the beginning (before some caches are populated). Here is a
stacktrace:

ERROR o.g.j.server.ServerRuntime$Responder - Error while closing the output
stream in order to commit response.

Any ideas? Is that a bug in Tomcat or I've done something wrong?
