> problem: _s:url_ tag on an application server running on JDK 1.5 (ex. JBoss 4.3) fails in some cases due to an incompatibility with JDK in class _org.apache.struts2.util.tomcat.buf.UDecoder_. Here an error stracktrace:

> The code is:
> {code:java}
> public static String URLDecode(String str, String enc, boolean isQuery) {
> if (str == null)
> return (null);
> // use the specified encoding to extract bytes out of the
> // given string so that the encoding is not lost. If an
> // encoding is not specified, use ISO-8859-1
> byte[] bytes = null;
> try {
> if (enc == null) {
> bytes = str.getBytes("ISO-8859-1");
> } else {
> bytes = str.getBytes(B2CConverter.getCharset(enc));
> }
> } catch (UnsupportedEncodingException uee) {
> if (log.isDebugEnabled()) {
> log.debug("Unable to URL decode the specified input since the encoding "+ enc + " is not supported.", uee);
> }
> }
> return URLDecode(bytes, enc, isQuery);
> }
> {code}
> Struts2 (ex. v. 2.3.31) is compiled with target JDK 1.5 but, method _getBytes(Charset)_ is only available since JDK 1.6.
> I suppose that this should be considered a bug because I suppose that Struts2 2.3.31, being compiled with target 1.5, should be considered compatible with JDK 1.5... but maybe this is a wrong assumption. I didn't find any explicit compatibility matrix on docs...
> The problem was *not* present in v. 2.3.24.
