Bug ID: 64839
Summary: HTTP2: Exception in thread
"http-nio-x.y.z-1090-ClientPoller"
java.lang.NullPointerException
Product: Tomcat 9
Version: 9.0.38
Hardware: HP
OS: Linux
Status: NEW
Severity: blocker
Priority: P2
Component: Catalina
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: -----
Sub-Component - Coyote
OS : Redhat Linux
Overview:
Embedded Tomcat version 9.0.38 is implemented to transport http/2 packets
between 2 systems (h2c connection). The number of threads configured in tomcat
is 200, all other values are the tomcat defaults.
We see the below NullPointerException is printed , after which the poller
thread is killed and tomcat is not processing any requests.
Exception in thread "http-nio-x.y.z-1090-ClientPoller"
java.lang.NullPointerException
We did not see any other Exceptions .
We suspect this is because the NullPointerException is not handled in
org.apache.tomat.util.net.NioEndPoint$Poller run() method .
On what scenarios does this occur ?
Can you please help fix this issue.
Build:
Embedded tomcat 9.0.38
Thanks in Advance!!
