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

             Summary: UnmodifiableList and UnmodifiableCollection are Externalizers
                 Key: ISPN-3831
                 URL: https://issues.jboss.org/browse/ISPN-3831
             Project: Infinispan
          Issue Type: Enhancement
          Components: Marshalling
            Reporter: Sanne Grinovero
            Assignee: Mircea Markus
             Fix For: 6.1.0.Final


These types are widely used in Infinispan and are using a slow path for Serialization:

- class java.util.Collections$UnmodifiableList
- class java.util.Collections$UnmodifiableCollection

This degenerates in slow UTF8 decoding and significant garbage being created.
