In fact the JVM was complaining that the library path was relative, not absolute. The error is in the findLibrary method of PluginLoader : instead of
1
| String libpath = parentDir.getPath() + File.separator + System.mapLibraryName(libname); |
it should be something like :
1
| String libpath = parentDir.getAbsolutePath() + File.separator + System.mapLibraryName(libname); |
Well there are several other changes involved to support correctly absolute paths, I'll post the code here so that it can be tested before submitting an official RFE + patch
All these changes are made in net.java.games.input.DefaultControllerEnvironment.
1) replace method scanControllers() with
1
2
3
4
5
6
7
8
9
10
11
12
| private void scanControllers() {
String pluginPathName = System.getProperty("jinput.controllerPluginPath");
if(pluginPathName == null) {
pluginPathName = "controller";
}
File[] dirs = getPotentialDirectories(pluginPathName);
for(int i = 0; i < dirs.length; i++) {
scanControllersAt(dirs[i]);
}
} |
2) replace method scanControllersAt(String path) with
1

| private void scanControllersAt(File file) {
try {
Plugins plugins = new Plugins(file);
Class[] envClasses = plugins.getExtends(ControllerEnvironment.class);
for(int i=0;i<envClasses.length;i++){
try {
if (DEBUG) {
System.out.println("ControllerEnvironment "+
envClasses[i].getName()
+" loaded by "+envClasses[i].getClassLoader());
}
ControllerEnvironment ce = (ControllerEnvironment)
envClasses[i].newInstance();
addControllers(ce.getControllers());
} catch (Exception e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}

(this is exactly the same method, except that it handles directly Files)
3) add the following methods

getPotentialPaths constructs the paths to be explored.
getPotentialDirectories makes sure that no directory will be searched twice by comparing files (trying to load the same library several times generates errors).
[EDIT] Sorry, my code indentation got screwed up by this damn forum
If you are interested, I can mail you the file.
