Description Marco Rietveld 2016-04-13 12:46:22 UTC

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.

Comment 7 Tomas Livora 2016-04-21 13:57:16 UTC

It seems that these commits fix the bug only partially. I have just tested it on the latest snapshot and while REST client calls with custom types work without any problems, direct REST calls still fail with the same exception:

org.kie.remote.services.exception.KieRemoteServicesDeploymentException: Could not unmarshall user-defined class instance parameter of type...

Comment 10 Tomas 'Sheldon' Radej 2016-04-25 12:16:45 UTC

Documented as a known issue for 6.3. We will adjust the documentation once a permanent fix is found.

Comment 11 Tomas Livora 2016-04-27 08:37:19 UTC

The tests that failed on the snapshot passed on the latest productized build so the issue is completely fixed.

Verified on BPM Suite 6.3.0 CR1
