JCas type not registered in JCasRegistry
Im making progress on my 3.x upgrade. Im now running into this error.
JCas type “my class type" defined in CAS type system and used in Java code, but was not registered in JCasRegistry.
I’ve always had a META-INF/org.apache.uima.fit/types.txt file defining the class paths to the types.. The types are generated with the 3.x version of jcasgen-plugin.
Is there another step to get the type registered?

Ok, this is perfectly normal. You create a CAS without specifying any type system.
Either you need to specify a type system description to the CasCreationUtils.createCas() or you need to use e.g the JCasFactory.createJCas() from uimaFIT which supports auto-discovery of type system descriptions (see https://uima.apache.org/d/uimafit-current/fit.html#_ugr.tools.uimafit.typesystem).

No.. this simple test fails
@Test
public void testJCas() throws Exception {
JCas jcas = CasCreationUtils.createCas().getJCas();
Pair p = new Pair(jcas);
}
org.apache.uima.cas.CASRuntimeException: JCas type "org.apache.ctakes.typesystem.type.util.Pair" used in Java code, but was not declared in the XML type descriptor.

Are you using any (custom) JUnit extensions or super-classes to your test classes that may already make calls to UIMA or reference JCas classes?

Thanks for getting back to me.. Ya, I did try putting it in a static block.. no luck there.

Should work in your unit test as well. Maybe you need to call it earlier.
Have you tried a static block in your unit test class?

Richard, The fix you suggested worked.. I added CasCreationUtils.createCas()(there is no newJCas() method as mentioned below.. Im using 3.4.1) and this resolved when running the application..
However, when I run my unit test that fix does not work..
Any idea why it would work in the application but not in a unit test..
Thanks

I suspect you hit this issue:
https://github.com/apache/uima-uimaj/issues/234
Try adding a dummy `CasCreationUtils.newJCas()` call when you initialize your application before any UIMA code is called.
I'm afraid, I have not found a UIMA-side fix for this yet... also not looking at the moment - quite complicated.
If it is not that issue, let me know.
Btw. there is also now an SPI-based mechanism to announce types and JCas classes that can be used as an alternative to the `types.txt`.
