The last version of imagej (1.51q) has issues when building the
javadocs for ij.gui.Plot
1. the javadoc '@see toStream()' should be '@see #toStream()'
2. however, even that does not work properly because the toStream
method is private and as such, excluded from the javadocs. This can
be fixed either by not linking to a private method (remove the whole
problematic @see link) or changing the javadoc access to private (set
access to private on the ant javadoc task)
