Caching null values

[anwfr]

It looks like caching NULL values is not supported by Ehcache 3.

A NullPointerException is raised from EhCache.put
Caused by: java.lang.NullPointerException: null

Can you confirm that this is intended behavior? Thx

Hello,

Thanks for your interest in Ehcache 3.

We request that users start the conversation on the google group ehcache-users before opening issues.

Indeed, you cannot cache a null value, this is also the behaviour of the JCache specification.

If you need this in your application, either create a sentinel value or wrap your values from your application.
