We are testing MDHT library to read CCD in multithreads. Any of *OptionalOperations class can throw UnsupportedOperationException. example:

14:34:13.592 [pool-1-thread-1] ERROR t.c.s.c.MultiThreadTest - null
java.lang.UnsupportedOperationException: null
at org.openhealthtools.mdht.uml.cda.consol.operations.AllergiesSectionEntriesOptionalOperations.getAllergyProblemActs(AllergiesSectionEntriesOptionalOperations.java:453)
at org.openhealthtools.mdht.uml.cda.consol.impl.AllergiesSectionEntriesOptionalImpl.getAllergyProblemActs(AllergiesSectionEntriesOptionalImpl.java:124)
at tr.com.srdc.cda2fhir.transform.CCDTransformerImpl.transformDocument(CCDTransformerImpl.java:180)
at tr.com.srdc.cda2fhir.MultiThreadTest.test(MultiThreadTest.java:107)

It is very likely some static data structures are not initialized yet before calling the helper.createQuery() method.

Any suggestion how to fix this multithreading problem? Thanks.

We had updated the library about 3 years or more ago for multi threading and did not run into any issues

Can you confirm the version of the libraries you are using ? Unfortunately we ran into some IP issues with HL7 regarding publishing the implementations and we do not have the libraries on Maven repo

we do have a private repo with the latest

Thanks

Sean, thanks for the info. Great that there is a multithread version. Please let me how to get the private repo.

I use this Maven dependency to pull in mdht version 3.1.1
<dependency>
<groupId>org.openehealth.ipf.modules</groupId>
<artifactId>ipf-modules-cda-mdht</artifactId>
<version>3.1.1</version>
</dependency>

Just curious, what kind of IP issues may be there with HL7?
