Hi Juan, You are using an old version of CAS, your best bet is to upgrade to a more recent version. You can check the latest CAS release here: https://github.com/apereo/cas/releases To minimized the change needed, use 5.3.7 would be Ok. 6.0.0 is better but you would need to change a fair bit in your enviornment (at least need to change to JDK11).
As for actually why this (i.e. ConcurrentModificationException) happen, I have search in the CAS PR and found the below: https://github.com/apereo/cas/pull/2649. If your problem is the same as the above, then maybe your problem exists in 5.1.x and is fixed in 5.2.x? Anyway, see if the above helps you!
