[infinispan-issues] [JBoss JIRA] (ISPN-2609) Infinispan SpringCache throws java.lang.NullPointerException: Null values are not supported!

[Marius Bogoevici (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-2609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753100#comment-12753100 ] 

Marius Bogoevici commented on ISPN-2609:
----------------------------------------

So, the problem *is* that Infinispan doesn't actually support {code}cache.put(key, null){code}, and nulls have to be stored wrapped in the cache.

As a fix we could go with Roland's fix directly in the SpringCache for 5.3.0. For previous versions, users would have to implement their own wrapper code (like Roland did) to work around storing nulls in the cache.
