Redis Plugin: NullpointerException when setting null

[ide-an]

I'm trying to use Redis Plugin with my Play 2.4 Java application.
When I set null value to Redis through Cache API, I get NullPointerException at

play-plugins/redis/src/main/scala/com/typesafe/play/redis/RedisCacheApi.scala

Line 88 in 0642612

throw new IOException("could not serialize: " + value.toString)

.
Redis Plugin supports String and Serializable, so there is a possibility of accepting null value as set parameter.

pac4j/play-pac4j#90 also refers to this problem.

Is this going to be addressed? It is quite a pain to check for nulls or NPEs when offering REDIS cache support.

The solution to this issue could be as simple as using String.valueOf(value) instead of value.toString, right? I'm in no way an expert, but this should be similar in Scala.
