Using jboss environment variables in PicketLink configuration does not work as expected. "jboss.server.config.dir" for instance will have file system path and using this variable "${jboss.server.config.dir}" under the picketlink.xml results in a failure on windows.

jboss.server.config.dir = C:\test\jboss\standalone\configuration

picketlink parses these out using Matcher.appendReplacement but does not attempt to do a "quoteReplacement" to deal with backslash and dollar sign resulting in the property value being read as:

jboss.server.config.dir = C:testjbossstandaloneconfiguration
