Exception when updating entry Set field with SpaceIndex

I have an entry which has a List<string> property annotated as so:

public Set<String> getItems() {
    return items;

I'm updating the items with a new TreeSet and then calling gigaSpace.write(MyEntry) to update. When I do that I see this exception:

java.lang.ClassCastException: com.j_spaces.core.cache.MemoryBasedEntryCacheInfo cannot be cast to com.j_spaces.core.cache.MultiValueIndexBackref at com.j_spaces.core.cache.AbstractMultiValueIndexHandler.consolidateMultiValueIndexOnXtnEnd(AbstractMultiValueIndexHandler.java:516) at com.j_spaces.core.cache.CustomMultiValueTypeDataIndex.consolidateIndexValueOnXtnEnd(CustomMultiValueTypeDataIndex.java:104) at com.j_spaces.core.cache.CacheManager.consolidateWithShadowEntry(CacheManager.java:4991) at com.j_spaces.core.cache.TypeData.updateEntryReferencesUnderXtn(TypeData.java:1166) at com.j_spaces.core.cache.TypeData.updateEntryReferences(TypeData.java:945) at com.j_spaces.core.cache.CacheManager.updateEntryInCache(CacheManager.java:3663) at com.j_spaces.core.cache.CacheManager.associateEntryWithXtn(CacheManager.java:2060) at com.gigaspaces.internal.server.space.SpaceEngine.performUpdateTemplateOnEntryCoreSA(SpaceEngine.java:5397) at com.gigaspaces.internal.server.space.SpaceEngine.performTemplateOnEntryCoreSA_impl(SpaceEngine.java:5069) etc...

Any idea what I might be doing wrong here?

I haven't been successful in reproducing this issue in a minimal test case. I have made some minor changes to the application where I observed this issue and it no longer occurs.

We would like to understand how these made this issue to go away.

The changes aren't directly related to this issue so I'm not sure I can really provide much more information. Sorry.
