Sanne Grinovero commented on ISPN-630:
--------------------------------------
it happens under high load only, not in any particular start/stop procedure.
I don't have a unit test for this, I can get some of these stacktraces when pushing
JMeter on high numbers against the Infinispan-enabled webapp - so that's many layers
of unknown things happening.
It might be interesting to consider that this was a single-node case, so - as confirmed by
the stacktrace - this marshalling is not happening from another node's transfer but
from the AsyncStore configured with String-based JDBC store with
org.infinispan.lucene.LuceneKey2StringMapper (MySQL - Amazon RDS)
I did have some isolated load tests which stress AsyncStore+JDBCStore+HSQLDB, but while
these are stressing a lot without failing they don't deal with big data dataset as
this failing JMeter run might be doing (but not sure of the data amount at the time of
failure)
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
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
