The lucene-jdbm-demo collection in the GS3 release binary wasn't getting built anymore. Sam found that unzipping the gs-jdbm-1.0.tar.gz resulting in a Broken Pipe error. Have taken the tar.gz from revision 23356, included the changes Sam made in 25568 (2 class files, 1 java file and updated the jar file with the same 2 class files and java file) and compressed it back to a tar.gz on Linux.
