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: [email protected]
Reporter: [email protected]
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.
java.lang.NullPointerException: Cannot invoke
"org.apache.tomcat.util.net.SocketWrapperBase.flush(boolean)" because
"this.this$0.socketWrapper" is null

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