Description
On old J9JVM version (cf. details under); the following package is unavailable: java.util.regex.* (eg. java.util.regex.Pattern)
XStream 1.4.2 uses this package in some extended converters only.
XStream 1.4.7 uses this package in the main XStream core class.
Following the MLUsers discussion:
http://thread.gmane.org/gmane.comp.java.xstream.user/8797
@Jorg says :
>We can load the class dynamically. This happens already e.g. for the types in the java.sql.* package that are also not available in some embedded envs.
Possible ways to fix this issue:
- put in the official website the minimal J9JVM version (eg. J9JVM > 2011)
- add regex package if missing (as Jorg says ?)
Today on my current J9JVM version, I can't use the latest XStream version (only 1.4.2 and without some converters). I mark this issue as major as this issue is non blocking for me.
@Jorg report that on J9JVM 2011 version; the regex package is here.

Ok Jörg, no problem
I should keep an old Xstream version to be compatible with device that use an old JVM version.
thanks for your answer

Hello Brice,
originally I thought we can load the classes java.util.regex.* dynamically, but those classes are not only used in converters, but also in some core elements and they are since version 1.4.7 even part of the public XStream API, so we are not able to switch to something else for internal use. Therefore I see no way to provide an official support for this old JVM version, sorry.
