[EvA] Failed compilation of EvA2 with icedtea6

[Marcel Kronfeld]

Hi again,

I have found some time to look into the issue. I found that the
sun.beans.editors are only used in a few cases to decide on which viewer
to instantiate. By handling that a bit differently, we can avoid to use
the sun-editors. The corresponding changes will be part of the next
release, which I hope to upload by the end of this week.
There will also be no more JPEGCodec required. Thanks for the proposal.

Best regards,
 Marcel Kronfeld
