Hello.
Please review a fix for jdk 9.
BufferedImage::getPropertyNames() was implemented according to
specification.
Notes:
- The properties map in the constructor is defined as <?,?>, which means
it can have non-String keys. Long time ago (in 2004) it was defined as
<String, ?> but was changed to <?,?> in some of (5054615, 5056707,
5060820, 5061476, 5073707). I am not sure, it is safe to change it back
to <String,?> or not, so I decided to filter out non-String keys.
- Unused isAlphaPremultiplied field was removed.
