Thanks always for maintaining free Java in Debian!

GNU Classpath fails to deserialize the attached FastTreeMap.fullCollection.version1.obj - see attached test case fis% jikes-sablevm TestReadExternalFormFromDisk.javafis% java -classpath .:/usr/share/java/commons-collections.jar TestReadExternalFormFromDisk at TestReadExternalFormFromDisk.main (TestReadExternalFormFromDisk.java:12) fis% /usr/lib/kaffe/bin/java -classpath .:/usr/share/java/commons-collections.jar TestReadExternalFormFromDisk java.io.InvalidClassException: class org.apache.commons.collections.FastTreeMap: Local class not compatible: stream serialVersionUID=8694543788950117671, local serialVersionUID=3247026550555952763 at java.io.ObjectInputStream.readClassDescriptor (ObjectInputStream.java:562) at TestReadExternalFormFromDisk.main (TestReadExternalFormFromDisk.java:12) This may instead be a bug in Jakarta Commons Collections - to which FastTreeMap.fullCollection.version1.obj belongs - but I assume the Collections authors succeed in deserializing using Sun's libraries This bug prevents the Jakarta Commons Collections build tests from succeeding
