This problem occurs only in test mode. Basically, I have several Call.get () calls in the tested class
Messages.get("api.parser.missing.id")
It exists in
public long getParserId() throws UnknownParserIdException {
if (parserEntity == null || parserEntity.parserId == 0) {
throw new UnknownParserIdException(Messages.get("api.parser.missing.id"));
}
return parserEntity.parserId;
}
In my test, I have the following
@Test
public void testSaveAndGetParserId() {
try {
addParserService.attachAppId(appId);
addParserService.attachParserJson(jsonToAttach);
addParserService.transformAttachedJson();
addParserService.saveParserEntity();
Long parserId = addParserService.getParserId();
boolean isPositive = parserId > 0;
assertTrue(isPositive);
ParserRepository parserRepository = new ParserRepository();
parserRepository.deleteParserById(parserId);
}
catch (MalformedParserException | UnknownAppIdException | UnknownParserIdException e) {
assertTrue(false);
}
}
Now when I run this test, I get the next NPE
[error] Test services.AddParserServiceTest.testTransformNoJsonAttached failed: java.lang.NullPointerException: null, took 0.09 sec

I have other classes and tests that are not part of my service package that are great for il8n classes.
Things I checked
- The message being called exists in messages
- The message file is specified in application.conf (which is included by application.test.conf)
- Removing the Message.get () call in my service class fixes the NPE, but I don't want to do this obviously.
