No, "lib" is automatically prepended (and ".so" appended too).
To debug this problem, you can add a static block
  static { System.out.println(System.getProperty("java.library.path")); }
in a class to check java.library.path, maybe this property is modified
when eclipse is launched.
You can also check that
 $ ldd /path/to/libvtkCommonJava.so
does not print any "not found" message.
