https://bz.apache.org/bugzilla/show_bug.cgi?id=64506 --- Comment #5 from Arvind Talari --- Hmmm.. actually may be it is not required, since org.apache.catalina.webresources.CachedResource#validateResources isn't conditionally validating. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

https://bz.apache.org/bugzilla/show_bug.cgi?id=64506 --- Comment #4 from Arvind Talari --- Thank you Mark for the quick turn around. Yes, we are able to build from source, being a race condition it isn't reproducible at will, we will need to manually simulate the race condition. Although, we haven't run into this issue, I am also wondering if a similar fix needs to be made in org.apache.catalina.webresources.Cache#getResources. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

https://bz.apache.org/bugzilla/show_bug.cgi?id=64506 --- Comment #3 from Mark Thomas --- Fixed in: - master for 10.0.0-M7 onwards - 9.0.x for 9.0.37 onwards - 8.5.x for 8.5.57 onwards 7.0.x is not affected. It would be great if you were able to test this. Our you able to build Tomcat from source? If not, I can provide a snapshot build for you to test. -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org

--- Comment #2 from Arvind Talari ---
Mark,
Thank you for your prompt reply.
The resource we found that was being looked up concurrently is
"/WEB-INF/classes/".
Thread 1 could be doing something like this
Thread#getContextClassLoader()#getResource("") for a class loader resource.
And Thread 2 could be doing
org.apache.catalina.WebResourceRoot#getResource("/WEB-INF/classes/") (from
org.apache.catalina.webresources.FileResource#getCodeBase) for a non-class
loader resource. This corresponds to the NPE stack trace shown in the
description

https://bz.apache.org/bugzilla/show_bug.cgi?id=64506 --- Comment #1 from Mark Thomas --- Thanks for the report and the careful analysis. I think the analysis has identified the root cause. I'l look into a fix. Out of curiosity, what resources are being looked up as class loader resources and non-class loader resources in parallel? -- You are receiving this mail because: You are the assignee for the bug. - To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
