Details:
The constructor of gnu.java.nio.charset.iconv.IconvProvider is
declared private, but I would like it to be public.
This is not a problem if an instance of
gnu.java.nio.charset.iconv.IconvProvider is to be obtained
by the method provider().
But the preferred usage is:
gnu.java.nio.charset.iconv.IconvProvider is listed in
META-INF/services/java.nio.charset.spi.CharsetProvider,
the class is loaded by Class.forName() and its instance
is obtained by Class.newInstance().
When gnu.java.nio.charset.iconv.IconvProvider is used this way,
its constructor must be public.
I wrote a simple subclass of java.nio.charset.spi.CharsetProvider
which has a private constructor and tried to use it with Sun's VM.
And as I expected, java.lang.IllegalAccessException was thrown.
So, although not clearly stated in the Sun's API document, the zero
argument constructor of subclasses of java.nio.charset.spi.CharsetProvider
must be public.
Making it public will violate the design of
gnu.java.nio.charset.iconv.IconvProvider
which uses singleton. Even so, I would like it to be public.
