ADLParsers for ADL 1.4/2.0

Hello,
I am currently trying to get a feeling for using the Java utilities that exist for openEHR and startet with the tools that exist as Maven repositories at https://mvnrepository.com.
I am currently experimenting with the ADLParser 1.0.71. As a test example I downloaded from the Clinical Knowledge Manager the archetype "openEHR-EHR-OBSERVATION.blood_pressure.v1" and exported it as an .adl-file. When parsing this file I receive an archetype instance but when invoking ToString() on it I get a StackOverflowException. Am I doing something wrong, is this a bug or are the archetype exports from CKM not specification compliant ?
Alternatively I think about rather using Archie as the toolbox for building my openEHR applications. But the ADLParser in Archie only supports ADL 2.0. Is there an equivalent for CKM supporting ADL 2.0 from where I can get a rich variety of archetype examples for experimenting ? Or are there converters that convert ADL 1.4 archetypes to ADL 2.0 ?
Greetings
Georg

Hello Georg,

The ADL workbench can convert adl 1.4 to adl 2.0 archetypes. It is available from the OpenEHR website. Archie parses and validates the output from the converted CKM correctly - in fact that is one of the included automated tests.
