---------------------------------------------------------
On further inspection, this may be an issue with how some of our custom
intereceptors use the conversion errors generated by struts. While it would be
convenient to mark it serializable, the issue seems to be more in how we are
dealing it with it.
We push conversion errors into the session momentarily to implement various
features, as part of the migration from older struts versions we started
pushing this map of conversion errors without checking serializability. In
older versions I believe it was just a map of <string,object> so we didn't even
consider it.
So feel free to close if this is not a problem with struts itself. Apologies!

We push conversion errors into the session momentarily to implement various
features, as part of the migration from older struts versions we blindly pushed
this class instead (whereas before it was simple String,Object values).

> Hello,
> Similarly to WW-4873, the {{ConversionData}} class is not marked as
> serializable, which interferes with replicated sessions, as Actions stored in
