@Cached not working in Play Framework

[Thomas Wiradikusuma]

Hi guys,

I think I found a bug in Objectify's @Cached with Play Framework. If I
have this class:

@Entity
@Unindexed
public class Test implements Serializable {
private static final long serialVersionUID = 1L;
// ... usual code
}

It's working OK. But when I add @Cached:

@Entity
@Unindexed
@Cached(expirationSeconds = 86400)
public class Test implements Serializable {
private static final long serialVersionUID = 1L;
// ... usual code
}

It will cause this exception:

Internal Server Error (500) for request GET /

Execution exception (In /app/controllers/Application.java around line
16)
ExceptionInInitializerError occured : null

Is this really a bug? Should I submit a bug in Objectify or is this
Play Framework's issue?

NPe on a system property check?

This is some very strange conflict between the appengine and play. I
can't even begin to imagine the cause. You should be able to isolate
a test case with some code that just makes this call:

SystemProperty.environment.value()

BTW I am out traveling (in Mérida at the moment) so I will not be
online much until next week.
