when uploading an archive file, there is an exception : java.lang.NegativeArraySizeException | at org.jboss.portal.cms.impl.jcr.command.StoreArchiveCommand.execute(StoreArchiveCommand.java:72) | at org.jboss.portal.cms.impl.jcr.JCRCommand.dispatch(JCRCommand.java:61) It is because of the zipEntry.getSize() that return -1 (unknown size). this is because of the use of ZipInputStream class. there is a turnaround with using the ZipFile class instead. see : http://forum.java.sun.com/thread.jspa?threadID=492219&messageID=2316626 I have opened a jira for this.
