cucumber-expressions: - sign withouth numbers matches as {double}

[mpkorstanje]

This in cucumber-jvm now fails with the latest cucumber-expressions snapshot:

    @Test
    public void generatesCopyPasteReadySnippetWhenStepHasIllegalJavaIdentifierChars() {
        String expected = "" +
            "@Given(\"I have {int} cukes in: my {string} red-belly!\")\n" +
            "public void i_have_cukes_in_my_red_belly(Integer int1, String string) {\n" +
            "    // Write code here that turns the phrase above into concrete actions\n" +
            "    throw new io.cucumber.java.PendingException();\n" +
            "}\n";
        assertEquals(expected, snippetFor("I have 4 cukes in: my \"big\" red-belly!"));
    }

With the snippet being:

@Given("I have {int} cukes in: my {string} red{double}belly!")
public void i_have_cukes_in_my_red_belly(Integer int1, String string, Double double1) {
    // Write code here that turns the phrase above into concrete actions
    throw new io.cucumber.java.PendingException();
}

Looks like the - is matched as a double.
