[infinispan-dev] Unexpected value returned from the cache

Hi, I'm frequently experiencing problems with a stack as this one: Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to [B at org.infinispan.lucene.SingleChunkIndexInput.<init>(SingleChunkIndexInput.java:49) The puzzling aspect is that the cast operation is applied on a type I'm retreiving from a Cache, which can not possibly be of a different type. I also happen to store some byte[] instances, but I never store a Class instance so I have no clue where this is coming from. I see these possible explanations: 1- Infinispan "forgets" to deserialize the object I'm requesting 2- It's picking the wrong Externalizer 3- the key is returning me a diffent object 4- I'm fooling myself with crap code Any known issue in the first 3 categories? Please don't ask me for trace logs, when I enable those the problem doesn't happen.. I could try again with specific categories. Sanne
