Description

The IRIResolver class has a public static iriFactory that is used for creating IRIs, but consumers never have a chance to call IRIResolver.iriFactory#setIsError or IRIResolver.iriFactory#setIsWarning because the iriFactory is used in a static block when the class is loaded. Any attempts to call either the setIsError or setIsWarning method throw the following exception:

java.lang.IllegalStateException: Cannot reinitialize IRIFactory after first use.
	at org.apache.jena.iri.impl.IRIFactoryImpl.initializing(IRIFactoryImpl.java:255)
	at org.apache.jena.iri.IRIFactory.setIsError(IRIFactory.java:579)
...

A simple test case that illustrates the problem is:

@Test
public void testIgnoreLowercaseViolation() {
  IRIResolver.iriFactory.setIsError(ViolationCodes.LOWERCASE_PREFERRED, false);
  IRIResolver.resolveIRI("http://EXAMPLE.com");
}
