So basically the following call | Arrays.asList(file.list()) | is failing inside Sun VM. For JBossVFS, the call is just getLastModified. So we need to figure out for which directory, this NPE is happening. | ArrayList(E[] array) { | if (array==null) | throw new NullPointerException(); | a = array; | } | This is the NPE we are seeing. IMO, we need to see why file.list() is returning null? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4156856#...
