How to get resources from inside plugin?

[kendzi]

In plugin loading class I try to get resource file from my plugin jar (kendzi3d.jar) using call:

getClass().getResource(“/resources/pluginProperties.properties”);

but in response I get:

jar:file:/C:/Documents%20and%20Settings/kendzi/Dane%20aplikacji/JOSM/plugins/ImportImagePlugin.jar!/resources/pluginProperties.properties

So url is pointing to file inside different plugin! ImportImagePlugin plugin have file with same name.

call to getClass()
result:
class kendzi.josm.kendzi3d.Kendzi3DPlugin (inside kendzi3d.jar)

It seems that it is bug with plugin class loader.

Or there is any other way to get files from my plugin jar?
