Release Note Text:
When Business Central is installed on IBM WebSphere, direct REST calls involving user-defined classes fail due to a serialization issue. The only workaround is using the Java REST client (if possible).
Target Release:

6.3.0.GA

Description of problem:

While https://bugzilla.redhat.com/show_bug.cgi?id=1299549 fixed the performance problems, unfortunately other problems, in particular custom-type serialization, were caused by the change.

Version-Release number of selected component (if applicable):

6.3.0 and 6.2.0.

This BZ is for 6.3.0

How reproducible:

Always

Steps to Reproduce:
1. Do a REST operation

Actual results:

Not all REST calls are completing correctly.

The 2 most common issues are either:

"Caused by: javax.xml.bind.PropertyException: property "com.ibm.jtc.jax.xml.bind.marshaller.CharacterEscapeHandler" must be an instance of type com.ibm.jtc.jax.xml.bind.marshaller.CharacterEscapeHandler, not org.kie.services.client.serial"
REST operations involving custom-type (user-defined) serialization fail

Expected results:

All REST calls complete successfully.
