Galder Zamarreño commented on ISPN-699:
---------------------------------------
Hmm, this is puzzling me now. Once I added more information about the exception, I see:
org.infinispan.CacheException: Type of data read is unknown. Byte read ('42') is
not amongst known reader indexes.
at
org.infinispan.marshall.jboss.ConstantObjectTable.readObject(ConstantObjectTable.java:259)
What the heck?
static final byte BUCKET = 42;
and
@Marshallable(externalizer = Bucket.Externalizer.class, id = Ids.BUCKET)
public final class Bucket
So, either:
- The HashMap contains a null for 42 index
- Or the HashMap does not contain the 42 index at all
- Or the ConstantObjectTable in use is not the one initially set up
This is stored in a simple HashMap, nothing fancy. Adding more logging to this.
occasional NullPointerException on unmarshalling in test application
