'ConcurrentModificationException in WildFly 26.0.1 and Java 17
We are in the process of upgrade of our platform to Wildfly 26.0.1 and Java 17. During recent load test we noticed that about 0.1% of calls failed due to exception thrown from elytron (see below). This same instance of WF26 worked fine with Java 8 - I understand this is due to change made in the implementation of HashMap#computeIfAbsent some time around Java9.
Has anyone came across same problem and knows whether workaround exists? The exception is below, thank you guys in advance!
