TOML TomlParserTest#float fails on master (3.0)

[cowtowncoder]

Just noticed that one test is now failing on master -- probably not due to TOML format module but maybe something in core JSON parser?

Anyway, it's

    @Test
    public void floats() throws IOException {
    }

in TomlParserTest (I renamed this from ParserTest)

@yawkat if you have a chance, would appreciate your help -- I am not sure which change in jackson-core might have caused this. One recent change to quoting of / by default (which caused a few test breaks) does not seem relevant, and I didn't think settings for fast-FP processing were changed for 3.0.

[cowtowncoder]

On fast-fp, settings I see are:

src/main/java/tools/jackson/core/StreamReadFeature.java:    USE_FAST_DOUBLE_PARSER(false),
src/main/java/tools/jackson/core/StreamReadFeature.java:    USE_FAST_BIG_NUMBER_PARSER(false)
src/main/java/tools/jackson/core/StreamWriteFeature.java:    USE_FAST_DOUBLE_WRITER(false)

that is, still defaulting to disabled by default for now. Although probably will want to enable them for 3.0 at some point.

Ok, I think this: FasterXML/jackson-databind#3651 -- and in particular change of JsonNodeFeature.STRIP_TRAILING_BIGDECIMAL_ZEROES default to false in 3.0 is what is somehow causing this.

Hmmh. Ok, decided to change configuration of ObjectMappers to make test pass.
Still not sure why normalization handling by TomlMapper differs. Oh well, something to look out for in future.
