That would be great, but part of the issue is that I get the same no matter what I use as a configuration file, valid or not valid, I still get the same exception. This is the most basic valid xml I have used (which produces the exception).:

<infinispan
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="urn:infinispan:config:9.0 http://www.infinispan.org/schemas/infinispan-config-9.0.xsd"
  xmlns="urn:infinispan:config:9.0">

  <cache-container>

  <local-cache name="dummyCache">
  </local-cache>

  </cache-container>

</infinispan>

I didn't use embedded as it gives me a slf4j log clash. I get that back, but I also get the same exception for some tests. This is the full stacktrace:

Classpath:
Actually at this point I am not sure of anything, but I changed the configuration of the application to point to infinispan2.xml (while the file really is called infinispan.xml) and then I get

Caused by: java.lang.IllegalArgumentException: Cache configuration does not exist 'class path resource [infinispan2.xml]'

so yes, I would say it is safe to assume that my xml is available and the application is picking it up.

In regards to versions. Yes all I did from a working setup to a non-working setup was to bump the version from 8.2.6-Final to 9.0.0-Final (and change the corresponding xml configuration with 9.0 version as shown in my example).

Why I was using infinispan-core? Fairly long story, all explained here: ClassNotFoundException after upgrading Infinispan from 8.2.6 to 9.0.0

I thought of the same thing. I am working on a minimum test case that contains no code directly related to our application. Will get back once that is done.

From the very first stacktrace I have more, but the second is about all I have. It seems like the stacktraces produced become very long and they get cut off.

This is what I got, but I would suspect it is pretty much the same as the long one I already pasted here: Infinispan stack trace - Pastebin.com

So I got a "working" test case now. GitHub - DBarbarian/CacheTest: Test cases of cache implementations

I have narrowed down the test to the very basics, so there is not even any cache class implementation there, because it wasn't necessary to reproduce the issue. It surfaces during initialization. In the master branch I have the test case for version 9.0.0, after building you can reproduce the error by running "mvn spring-boot:run". I have also created a branch called version-8.2.6 for comparison where I am using version 8.2.6 of inifinispan instead starting up beautifully.
