Calling Row.get(…) twice for the same column fails

[mp911de]

Calling Row.get(…) twice using the same column either fails with IndexOutOfBoundsException or returns an invalid result.

Version: 0.8.0-alpha1

SQL:

INSERT INTO legoset (name, manual) VALUES (?, ?)

Called Statement.returnGeneratedValues() and then Row.get("ID")

java.lang.IndexOutOfBoundsException: expected: 0 <= start(2) <= start + length(1) <= buf.capacity(2)

Reproducer:

connection.createStatement("INSERT INTO legoset (name, manual) VALUES (?, ?)")
		.bind(0, "Hello")
		.bind(1, 1)
		.returnGeneratedValues()
		.execute()
		.flatMap(it -> it.map((row, rowMetadata) -> {

			row.get("id");
			row.get("ID");
			return new Object();
		}))
		.as(StepVerifier::create)
		.expectNextCount(1)
		.verifyComplete();

Allright. Thanks for reporting @mp911de .
