----------------------------------

             Summary: SerializationConfiguration.advancedExternalizers() map should not be mutable
                 Key: ISPN-7634
                 URL: https://issues.jboss.org/browse/ISPN-7634
             Project: Infinispan
          Issue Type: Bug
          Components: Configuration, Core
    Affects Versions: 9.0.0.CR2
            Reporter: Dan Berindei
            Assignee: Dan Berindei
            Priority: Minor
             Fix For: 9.0.0.Final


Currently {{SerializationConfiguration.advancedExternalizers()}} returns a mutable {{HashMap}}. We only read it once on startup, so modifying it won't break anything, but it should be immutable to make it clear that externalizers cannot be added at runtime.
