B.13.3. Requesting a Full Byte Array

How can I request the JBoss Data Grid return a full byte array instead of partial byte array contents?

As a default, JBoss Data Grid only partially prints byte arrays to logs to avoid unnecessarily printing large byte arrays. This occurs when either:

  • JBoss Data Grid caches are configured for lazy deserialization. Lazy deserialization is not available in JBoss Data Grid's Remote Client-Server mode.
  • A Memcached or Hot Rod server is run.
In such cases, only the first ten positions of the byte array display in the logs. To display the complete contents of the byte array in the logs, pass the -Dinfinispan.arrays.debug=true system property at start up.

Example B.1. Partial Byte Array Log

2010-04-14 15:46:09,342 TRACE [ReadCommittedEntry] (HotRodWorker-1-1) Updating entry 
(key=CacheKey{data=ByteArray{size=19, hashCode=1b3278a, 
array=[107, 45, 116, 101, 115, 116, 82, 101, 112, 108, ..]}} 
removed=false valid=true changed=true created=true value=CacheValue{data=ByteArray{size=19,

version=281483566645249}]
And here's a log message where the full byte array is shown:
2010-04-14 15:45:00,723 TRACE [ReadCommittedEntry] (Incoming-2,Infinispan-Cluster,eq-6834) Updating entry
