Galder Zamarreño updated ISPN-630:
----------------------------------
Attachment: Better_reporting_for_null_adapter_and_more_log_at_write_time.zip
Find attached a zip containing a patched Infinispan core jar with better reporting for
when the adapter is null and some extra logging for when a ConcurrentHashSet is written.
In particular, 0x03 id that signals predefined object type can only be written for a
ConcurrentHashSet if at writing time anything other than null is returned from the
predefined object type lookup.
Since we're dealing with a concurrent collection, I've played around with a test
that marshalls/unmarshalls a CHS while another thread adds/removes to it, in case the
issue is due to concurrent modification/marshalling.
When you run your tests, enable TRACE logging for
org.infinispan.marshall.jboss.ConstantObjectTable class. Logging won't be verbose.
Finally Sanne, I'm curious to know whether when you get this NPE, the exception
*always* looks exactly the same.
NullPointerException during object unmarshalling
------------------------------------------------
Key: ISPN-630
URL: https://jira.jboss.org/browse/ISPN-630
Project: Infinispan
Issue Type: Bug
Components: Marshalling
Affects Versions: 4.1.0.Final
Reporter: Sanne Grinovero
Assignee: Galder Zamarreño
Fix For: 4.2.0.BETA1, 5.0.0.BETA1
Attachments: Better_reporting_for_null_adapter_and_more_log_at_write_time.zip
It appears the ExternalizerAdapter was not added to the readers, or that
input.readUnsignedByte() reads a wrong identifier value.
Not easy to reproduce, get this sometimes under load:
Exception in thread "Scarlet/Lucene service thread index reopening thread-1"
java.lang.NullPointerException
