Rename ParserException to MeasurementParseException

[keilw]

A rather generic ParserException can be found at least in JDK Nashorn, but otherwise both the JDK and other JSRs either call it ParseException (like java.text.ParseException) or *ParseException (like MonetaryParseException, DateTimeParseException, etc.)

It is not the most urgent case, but with other proposals like #39 that also would require adding a new name and deprecate the old one, it's worth do mention this as well. A new exception could be called MeasurementParseException.

[keilw]

Removed usage of ParserException from a format() method, so I would leave it for now, and close this one. Leaving #58 open.

[keilw]

Reopened this as it would be cleaner and more consistent with JSR 310, 354 and others.

The idea would be to leave ParserException in the API 2.0 if we have to (for backward compatibility) but simply extend a new MeasurementParseException and mark ParserException deprecated.

Please vote on either:

[keilw]

A) Rename ParserException to MeasurementParseException for consistency with a large number of APIs and frameworks (JSR 310, 354, Jackson, Gradle,...) marking the old one deprecated.

[keilw]

B) Keep ParserException as it is.

Why not MeasureParseException (makes more sense and shorter) ?

[desruisseaux]

But this exception can also occur while parsing Unit objects instead of Measure objects, isn't it?

[keilw]

Yes, but Measure is not an API element any more, Quantity is. Having the base exception start with Measurement, I thought MeasurementParseException (similar to DateTimeParseException in Date/Time) would be a good name. We have a QuantityFormat interface now, so both Unit and Quantity can be parsed, which is why UnitParseException won't be enough.

[keilw]

Although it is only an SPI element of Indriya, we have a Measurement interface ever since JSR 363, so calling it MeasurementParseException sounds more consequent since this exception will also extend MeasurementException. Compared to IncommensurableException it is just one more character ;-)
