Error retrieving composition by UUID FLAT & RAW

[dileep-ehr]

I am getting the following errors retrieving vitals compositions (template file set and OPT attached) committed using ECISFLAT in v1.3.0

FLAT

Error 500 #1.0.0 Invocation exception to method:retrieve:javax.xml.bind.UnmarshalException: Unable to create an instance of org.openehr.jaxb.rm.ItemStructure
 - with linked exception:
[java.lang.InstantiationException]

RAW
``Error500 #1.0.0 Invocation exception to method:retrieve:java.lang.StackOverflowError
###Sequence of events
In Pulse/Heart beat, the Rate field has runtime name constraint of Pulse Rate/Heart Rate. As I was not sure how to do this using ECISFLAT, tried the following options.

1. "/content[openEHR-EHR-SECTION.vital_signs.v0]/items[openEHR-EHR-OBSERVATION.pulse.v1]/data[at0002]/events[at0003]/data[at0001]/items[at0004, 'pulse_rate/value']": "72,/min",
2. "/content[openEHR-EHR-SECTION.vital_signs.v0]/items[openEHR-EHR-OBSERVATION.pulse.v1]/data[at0002]/events[at0003]/data[at0001]/items[at0004, 'pulse_rate']|value": "72,/min",

Both options successfully committed, and I was able to retrieve them using ECISFLAT but not using FLAT or RAW. After that, even if I commit without the name constraining FLAT & RAW are giving above error.

Looks like the corruption to the JSON structure in one composition is affecting all compositions that use the same template.

Sample compositions with and without name constraint

Option 1 - with name constraint
