Description

The lib option doesn't work and, hence, you cannot add put a solr extension jar in a specified library. As a workaround you can put the jar into <instance dir>/lib

It doesn't work for at least two reasons:
1) The instance dir is added twice: once in initLibs, and another time in addToClassLoader
2) When I fixed this, I found out that the filtering class for addToClassLoader doesn't work properly.

A rough fix is as follows, but it, probably, can't make use of Solr variables such as solr.solr.home. This is code changed in initLibs, I commented out incorrect lines:

        } else if (null != path) {
          //final File file = FileUtils.resolvePath(new File(loader.getInstanceDir()), path);
          final File file = new File(path);
          loader.addToClassLoader(file.getParent(), new FileFilter() {
            @Override
            public boolean accept(File pathname) {
              //return pathname.equals(file);
              return true;
            }
          }, false);
