Just created a new PR to have a Travis build and be able to push changes to the PR.

@chrjohn A bit off topic question: Why is there no way to get field value without catching an exception?

try {   
	if (msg.isSetField(Text.FIELD)) {
		String text = msg.getString(Text.FIELD);

		// ...
	}
} catch (FieldNotFound e) {
	logger.error("FieldNotFound:", e);
}

Either:

Optional<String> text = msg.getStringOpt(Text.FIELD);

or:

@Nullable Optional<String> text = msg.getStringOrNull(Text.FIELD);

would be much easier to use.

Thank you and sorry for offtopic question.

Hi @MartyIX ,
what about #162 ? ;)
Would that suit your needs? If you'd like something to be added just open another PR.

Thanks and Happy Easter!
Cheers,
Chris.
