Problem Description:

When you serialize a cfcatch struct, the JSON doesn't match the same data format at all.
stackTrace switches from a string to an array
tagContext disappears completely

Steps to Reproduce:

try {
 sdfrsd();
} catch( any e ){
 writeDump( e );
  writeDump( deserializeJSON( serializeJSON( e ) ) );
}

Run that code on trycf.com and you can see that the two dumps differ significantly.  This makes it a pain to deal with ColdFusion errors that have been serialized into JSON.  It is an unexpected behavior, and also doesn't match Lucee Server, which correctly serializes the cfcatch struct to match the exact same data.

Actual Result:

stackTrace switches from a string to an array
tagContext disappears completely

Expected Result:

stackTrace is represented the same
tagContext does not disappear

Any Workarounds:

Do some sort of custom serialization.
