Creating STRUCT from Java object is not working as expected using ojdbc8.jar with Spring jdbc

We are seeing the below values when we dump the STRUCT object from the application using Oracle 19c Database. The values for the field "PREFERENCE_KEY" and "PREFERENCE_VALUE" is not getting mapped properly. Could someone please suggest how to fix this issue?


Struct Values: name = TYPE_PREFERENCE_ITEM

length = 5

PREF_ITEM_ID = 5802463

P_ID = 63035

PREFERENCE_KEY = ???

PREFERENCE_VALUE = ???

PARENT_PREF_ID = 0


Code snippet:

StructDescriptor sdesc = StructDescriptor.createDescriptor(

this.structName, wrappedConnection);

STRUCT[] structList = new STRUCT[data.size()];

int count = 0;

for (Map<String, Object> param : data) {

STRUCT struct = new STRUCT(sdesc, wrappedConnection, param);

structList[count++] = struct;

System.out.println("structList - "+count+ " : " + struct.dump());

}


ArrayDescriptor desc = new ArrayDescriptor(typeName, wrappedConnection);

return new ARRAY(desc, wrappedConnection, structList);
