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

             Summary: ArrayIndexOutOfBoundsException in BoundedOffHeapDataContainer.removeSegments
                 Key: ISPN-10518
                 URL: https://issues.jboss.org/browse/ISPN-10518
             Project: Infinispan
          Issue Type: Bug
          Components: Core, State Transfer
    Affects Versions: 10.0.0.Beta5, 9.4.16.Final
            Reporter: Dan Berindei
            Assignee: Will Burns
             Fix For: 10.0.0.CR2, 9.4.17.Final


When the {{data-segmentation}} feature is disabled, the data container is not segmented, but {{BoundedOffHeapDataContainer.removeSegments}} still uses {{DefaultSegmentedDataContainer.getMapForSegment}} internally, and gets an  {{ArrayIndexOutOfBoundsException}}:

The exception doesn't prevent the state transfer from finishing, but if the segments become owned by the local node again in the future, the cache may return the outdated values that were not removed because of the exception.
