question: public static ClassLoader bootCallerClassLoader ( ) { return BootstrapClassLoader . getBootstrapClassLoader ( ) ; }
target:  This method must be provided by the vm vendor, as it is used by org.apache.harmony.luni.util.MsgHelp.setLocale() to get the bootstrap ClassLoader. MsgHelp uses the bootstrap ClassLoader to find the resource bundle of messages packaged with the bootstrap classes. The reference implementation of this method uses the getStackClassLoader() method. Returns the ClassLoader of the method that called the caller. i.e. A.x() calls B.y() calls callerClassLoader(), A's ClassLoader will be returned. Returns null for the bootstrap ClassLoader.
