Describe the bug
When using the $validate operation with the hapi-fhir-jpaserver-starter a NP is raised by the UnknownCodeSystemWarningValidationSupport when providing a resource to validate:

ca.uhn.fhir.rest.server.exceptions.InternalErrorException: Failed to call access method: java.lang.NullPointerException
        at ca.uhn.fhir.rest.server.method.BaseMethodBinding.invokeServerMethod(BaseMethodBinding.java:272)
...
  
Caused by: java.lang.NullPointerException: null
        at ca.uhn.fhir.context.support.DefaultProfileValidationSupport.fetchCodeSystemOrValueSet(DefaultProfileValidationSupport.java:182)
        at ca.uhn.fhir.context.support.DefaultProfileValidationSupport.fetchCodeSystem(DefaultProfileValidationSupport.java:160)
        at org.hl7.fhir.common.hapi.validation.support.ValidationSupportChain.fetchCodeSystem(ValidationSupportChain.java:217)
        at org.hl7.fhir.common.hapi.validation.support.BaseValidationSupportWrapper.fetchCodeSystem(BaseValidationSupportWrapper.java:86)
        at org.hl7.fhir.common.hapi.validation.support.UnknownCodeSystemWarningValidationSupport.validateCodeInValueSet(UnknownCodeSystemWarningValidationSupport.java:40)
        at org.hl7.fhir.common.hapi.validation.support.ValidationSupportChain.validateCodeInValueSet(ValidationSupportChain.java:289)
        at org.hl7.fhir.common.hapi.validation.support.BaseValidationSupportWrapper.validateCodeInValueSet(BaseValidationSupportWrapper.java:107)

Expected behavior
Don't throw a NP at L180 or don't call fetchCodeSystem from UnknownCodeSystemWarningValidationSupport with null as codesytem:

			// System can take the form "https://url|version"
			String system = theSystem;
			if (system.contains("|")) {

Environment (please complete the following information):

  • HAPI FHIR Version 5.5.1
  • OS: OSX

Additional context
Will provide a PR to fix the behaviour.
