The exceptions from my initial post #4499 are corrected with PMD 7 and the snapshot maven plugin.
However, I get a different set of exceptions with PMD 7.0.0:
[WARNING] Exception applying rule ImplicitSwitchFallThrough on file file:///home/luc/sources/eclipse/hipparchus/hipparchus-ode/src/main/java/org/hipparchus/ode/events/FilterType.java, continuing with next rule
org.apache.commons.lang3.exception.ContextedRuntimeException: java.lang.NullPointerException
Exception Context:

case UNINITIALIZED :

[INFO] PMD version: 7.0.0-SNAPSHOT
Note that I did not fix the warnings from my 6.x.x version of mpd-ruleset.xml before running the check, but I doubt these warning are related to the exceptions.
