intermittent failure: testRemoteAnon throws NPE

Description (Last modified by mroy)

The NPE is on the second line of ModelServiceApi?: 

if (adminUsersCache.containsKey(userId)) {
  Boolean isSystemUser = (Boolean) adminUsersCache.get(userId);
return isSystemUser.booleanValue();
}

There is a rare case where the if statement returns true but the following get returns null which threw the NPE. This looks to be a concurrency issue on the LRUMap adminUsersCache.

To fix: 

Boolean isSystemUser = (Boolean) adminUsersCache.get(userId);
if (isSystemUser != null) {
  return isSystemUser.booleanValue();
}

and synchronize adminUsersCache.
