[jbosstools-issues] [JBoss JIRA] (JBIDE-15839) Exception while saving Provider in JAX-RS application

[Xavier Coulon (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-15839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12850897#comment-12850897 ] 

Xavier Coulon commented on JBIDE-15839:
---------------------------------------

Fixed the problem which occurred only when the problem severity as set to
'ignore' level. In that particular case, no IMarker would be created, thus
returning a null reference, which lead to NPE.

So, to reproduce the bug, the following code example should work:

{code}
@Provider
public class SimpleMessageBodyReader {

	@Override
	public boolean isReadable(Class<?> type, Type genericType,
			Annotation[] annotations, MediaType mediaType) {
		// TODO Auto-generated method stub
		return false;
	}

	@Override
	public String readFrom(Class<String> type, Type genericType,
			Annotation[] annotations, MediaType mediaType,
			MultivaluedMap<String, String> httpHeaders, InputStream entityStream)
			throws IOException, WebApplicationException {
		// TODO Auto-generated method stub
		return null;
	}

}
{code}

then, set the JAX-RS Validation problem level to "Ignore" for the "Missing Provider Implementation" type of problem (in the JAX-RS Providers sub-category), and finally, validate the project (or do a clean/build).
