Tomcat NioEndpoint - Error running socket processor

Question

In a Spring Boot production app, the following exception is occasionally thrown:

o.a.t.u.n.NioEndpoint : Error running socket processor

java.util.NoSuchElem         


        

Answer 1

This seems to be caused by a JRE issue:

http://hg.openjdk.java.net/jdk/jdk/rev/01d8eae542ff

https://bugs.openjdk.java.net/browse/JDK-8218889

It was fixed with

• 11.0.8 b01
• 11.0.7 b04
• 8u261 b05

Are you using an affected JRE version?

As for the second issue you mentioned:

https://bugs.openjdk.java.net/browse/JDK-8241248

This is an option issue (but mentions a workaround).

Please look into both issues, try to update for addressing the first issue and see if your can apply the workaround as long as no fix is available for the second issue.
