Please review this PR and [CSR
](https://bugs.openjdk.org/browse/JDK-8314974)which clarifies behavior for
BreakIterator instances when text has not been set.
For example, calling `BreakIterator.getWordInstance().next();` has an
ambiguous result.
A boundary searching operation was called but no text was supplied. Is the
result an exception, 0, -1 (BreakIterator.DONE), or something else? In reality,
the operation will be performed on any empty string.
This change makes it apparent that failing to set the text will cause the
BreakIterator instance to default to a `StringCharacterIterator` with an empty
string (equivalent to calling setText("")).
