Given that GPL+classpath exception is rejected in the same way as LGPL
by those requesting for a licensing change, there is no need for
change if the end result is the same.

- subsequent to discussions on the mailing list, tentatively changing the license to GPL+classpath exception instead of the less clear LGPL+classpath.
  Note that GPL+classpath is the same license terms as JDK 7.
