[Bug 63251] [JDK-8194653] Deadlock in FileSystems.getDefault on catalina startup
https://bz.apache.org/bugzilla/show_bug.cgi?id=63251 --- Comment #4 from Mark Thomas --- It would be worth testing with Java 8 u231 when released - it is reported as fixed in that version. Meanwhile, you can see if the Spring Boot team is willing to add the workaround to Boot. -- 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=63251 --- Comment #3 from harri...@gmail.com --- (In reply to harristr from comment #2) > The work-around of pre-loading the default FileSystem does not appear to > solve the problem for logging, or maybe it only reduced the frequency of the > occurrence. I am still seeing the following stacktrace from a Spring Boot > Microservice running Tomcat 9.0.22 with JDK 1.8.0_222 64-bit on RedHat 7.5: After further investigation I think this work-around actually CAUSED the "deadlock" I am experiencing. I never saw this using Tomcat 9.0.17, it only manifested after an upgrade directly to 9.0.22. In an environment such as mine (a SpringBoot Microservice), Tomcat is NOT running in the main thread or starting first, Spring Boot is. This means the probability of reaching the "deadlock" is higher since Spring Boot is the one running first and Tomcat is coming up in a different thread but is now trying to prime the FileSystem right away. I included more of the thread dump below.
