TYPE_STRING does not handle unicode ----------------------------------- Key: JGRP-2061 URL: https://issues.jboss.org/browse/JGRP-2061 Project: JGroups Issue Type: Bug Reporter: Cody Ebberson Assignee: Bela Ban Fix For: 4.0.6 In several places throughout the org.jgroups.util.Util class, it is assumed that Strings are one byte per character. For example, see objectToByteBuffer lines 561-567: https://github.com/belaban/JGroups/blob/master/src/org/jgroups/util/Util.... {code:java} case TYPE_STRING: String str=(String)obj; int len=str.length(); ByteBuffer retval=ByteBuffer.allocate(Global.BYTE_SIZE + len).put(TYPE_STRING); for(int i=0; i < len; i++) retval.put((byte)str.charAt(i)); return retval.array(); {code} This code will incorrectly encode any String with non ASCII encoding. There are several options to fix. You could use str.getBytes(StandardCharsets.UTF_8) to get a proper byte encoding, or you could use the existing TYPE_SERIALIZABLE code path.
