A SafeUTF

Version:

$Revision: 1174 $ $Id: SafeUTF.java 1174 2006-08-02 14:14:32Z timfox $ There is a "bug" in JDK1.4 / 1.5 DataOutputStream.writeUTF() which means it does not work with Strings >= 64K serialized size. See http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4806007 We work around this by chunking larger strings into smaller pieces. Note we only support TextMessage and ObjectMessage bodies with serialized length >= 64K We DO NOT support Strings written to BytesMessages or StreamMessages or written as keys or values in MapMessages, or as String properties or other String fields having serialized length >= 64K This is for performance reasons since there is an overhead in coping with large Strings
