Typically in ImageJ output sent to the standard system streams by calls such as System.out.println(...) are suppressed. Redirecting the standard output streams makes this output appear in ImageJ's log console, analogous to using the IJ.log() method. This is particularly useful for debugging imported code and for writing classes that are independent of ImageJ.

This library is built into the ImageJ 1.47m daily build as the ij.io.LogStream class. You can redirect System.out and System.err messages to the Log window by enabling debug mode in Edit>Options>Misc.
