[cas-user] CAS 5.3.2 ConcurrentModificationException when creating TGT

[Chris Luczkow]

Hi -

We're seeing this intermittent exception when running under heavy load:

java.util.ConcurrentModificationException: null

at java.util.ArrayList.sort(ArrayList.java:1464) ~[?:1.8.0_201]

at java.util.Collections.sort(Collections.java:175) ~[?:1.8.0_201]

at org.springframework.core.OrderComparator.sort(OrderComparator.java:167) ~[spring-core-4.3.18.RELEASE.jar:4.3.18.RELEASE]

at org.apereo.cas.rest.factory.ChainingRestHttpRequestCredentialFactory.fromRequestBody(ChainingRestHttpRequestCredentialFactory.java:41) ~[cas-server-core-rest-5.3.2.jar:5.3.2]

at org.apereo.cas.support.rest.resources.TicketGrantingTicketResource.createTicketGrantingTicketForRequest(TicketGrantingTicketResource.java:114) ~[cas-server-support-rest-5.3.2.jar:5.3.2]

at org.apereo.cas.support.rest.resources.TicketGrantingTicketResource.createTicketGrantingTicket(TicketGrantingTicketResource.java:66) ~[cas-server-support-rest-5.3.2.jar:5.3.2]

Wondering if this is a known issue or how to troubleshoot further.

Thanks

Chris
