[jira] [Comment Edited] (GEODE-6099) Useless error message is logged when Geode fails to apply delta

------------------------------------------------------------

It is tempting to think that the error message is useful in the context of a single interaction (transaction), since the error message does report the {{Key}} along with the {{Region}} upon which the {{Delta}} error occurred.

However, if I have a high volume of interactions/transactions on the same _Key/Value_ (_Entry_) in the same {{Region}}, is not apparent which {{Delta}} is in error.  Therefore, the error message is useless because I already know the {{Key}} and {{Region}} to which the entry (i.e. the "delta") is being written.

What, I want to know is which "delta" (i.e. change) caused the error and why!

> When serializing application domain objects using {{Deltas}} (i.e. application domain types implement {{org.apache.geode.Delta}}) between client and server, Apache Geode will log a completely *useless* error message to the log output (e.g. file) when Apache Geode encounters a problem applying the "delta"...
> {code}
> [info 2018/11/27 22:14:23.196 PST <ServerConnection on port 64301 Thread 1> tid=33] Error applying delta for key X of region /Example
> {code}
> Minimally, providing the underlying Exception's (i.e. {{cause}}) message would, perhaps, provide some relief and insight!
> This is with the {{log-level}} already set to {{config}}.  I should not have to set the {{log-level}} to {{debug}} in order to ascertain the problem.  At {{debug}}, or especially {{trace}}, I would expect to see a _Stack Track_ even.
