Michal Linhard commented on ISPN-2787:
--------------------------------------
The client stress test that this appeared in was actually JDG 6.1.0.ER10 with patch for
ISPN-2776 (changed only MIMECacheEntry class)
but this is about the problem with replaceInternal return type being boolean, which
doesn't correspond to possible return values of ReplaceCommand.perform (possibly any
object and also null) - second possible exception here is ClassCastException.
NPE after ReplaceCommand

Seems like the NPE is caused by ReplaceCommand.perform returning null:
