WeakHashSet changes for revisions 10795:10796

Changes in this commit seem to be the result of some "auto reformat" tool execution. The Java - GeoAPI - GeoTools import ordering is altered, imports used only in Javadoc are lost and the encoding of non-ASCII characters is broken. This commit has been reverted, except for the removal of really unused imports which are kept removed.
