  This method will search for `resource` in different places. The search order is as follows:

  1. Search for `resource` using the thread context class loader under Java2. If that fails, search for `resource` using the class loader that loaded this class (`Loader`). Under JDK 1.1, only the the class loader that loaded this class (`Loader`) is used.

  2. Try one last time with `ClassLoader.getSystemResource(resource)`, that is is using the system class loader in JDK 1.2 and virtual machine's built-in class loader in JDK 1.1.

### isJava1
