> When deploying Liferay 6.1 I'm getting the following error
> {code}08:08:38,561 WARN  [org.jboss.as.server.deployment.module.module-extension-list-processor] (MSC service thread 1-1) Could not find Extension-List entry ExtensionListEntry [name=javax.crypto, title=crypto] referenced from ResourceRoot [root="/D:/Development/Servers/jboss-as-7.1.0.CR1b/content/ROOT.war/WEB-INF/classes"]{code}
> After some debug on the JBoss 7.1 CR1b source I found that it uses the java.ext.dirs property to find the ext libs, but since java 1.6 the property returns a classpath formated string with more than one path where the extensions are located(http://docs.oracle.com/javase/tutorial/ext/basics/install.html), but on the JBoss code I found that it's trying to parse the property value as a File path directly.
> As you can se on the ServerEnvironment.java line 292
> {code}// Java system-wide extension dirs
>         javaExtDirs = getFilesFromProperty(JAVA_EXT_DIRS, props);{code}
> and line 524
> {code}
>  private File getFileFromProperty(final String name, final Properties props) {
>         String value = props.getProperty(name, null);
>         if (value != null) {
>             File f = new File(value);
>             return f;
>         }
>         return null;

> This is causing that the server can´t find the extensions and warning about it.
