           Summary: com.sun.image.codec.jpeg doesn't work with ImageJ
           Product: IcedTea
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: IcedTea
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: adam at spicenitz.org


ImageJ is a widely used image processing system for Java. Unfortunately, it
doesn't build with icedtea6, because there are missing methods in
com.sun.image.codec.jpeg.

It also throws a runtime error when attempting to save a JPEG, because
com.sun.image.codec.jpeg.JPEGImageEncoder is supposed to be an interface, not a
class.


First, the source problem:
    [javac] /home/agoode/ij-source/source/ij/plugin/JpegWriter.java:46: cannot
find symbol
    [javac] symbol  : method setHorizontalSubsampling(int,int)
    [javac] location: class com.sun.image.codec.jpeg.JPEGEncodeParam
    [javac]                             param.setHorizontalSubsampling(1, 1);
    [javac]                                  ^
    [javac] /home/agoode/ij-source/source/ij/plugin/JpegWriter.java:47: cannot
find symbol
    [javac] symbol  : method setHorizontalSubsampling(int,int)
    [javac] location: class com.sun.image.codec.jpeg.JPEGEncodeParam
    [javac]                             param.setHorizontalSubsampling(2, 1);
    [javac]                                  ^
    [javac] /home/agoode/ij-source/source/ij/plugin/JpegWriter.java:48: cannot
find symbol
    [javac] symbol  : method setVerticalSubsampling(int,int)
    [javac] location: class com.sun.image.codec.jpeg.JPEGEncodeParam
    [javac]                             param.setVerticalSubsampling(1, 1);
    [javac]                                  ^
    [javac] /home/agoode/ij-source/source/ij/plugin/JpegWriter.java:49: cannot
find symbol
    [javac] symbol  : method setVerticalSubsampling(int,int)
    [javac] location: class com.sun.image.codec.jpeg.JPEGEncodeParam
    [javac]                             param.setVerticalSubsampling(2, 1);



Second, the runtime problem:

com.sun.image.codec.jpeg.JPEGImageEncoder, but interface was expected
