UnsupportedOperationException: Collision adding composited set with no SetMutator set
is thrown when Spring reads the below configuration. According to the documentation of API CompositeMap, it looks like setMutator is to be set somewhere, but not sure how. Besides, this didn't seem to be problem when Java8 & Spring 3 were used, the exception is thrown when I tried to upgrade Java to 11 and Spring to 5.
<bean>
<bean id="EntityToRepository" class="org.apache.commons.collections4.map.CompositeMap">
<constructor-arg ref="repo1"/>
<constructor-arg ref="repo2"/>
<constructor-arg ref="myMapMutator"/>
</bean>
full stack is like below. It looks like, even though CompositeMap is used, the issue ended up in CompositeSet, in which setMutator wasn't set. And CompositSet was triggered in CompositeMap's hashCode method.
