question: @ Override public boolean isModified ( ) { if ( _dependencyList . isModified ( ) ) { return true ; } synchronized ( _pathList ) { _newPathList . clear ( ) ; loadPaths ( _newPathList ) ; Collections . sort ( _newPathList ) ; return ! _newPathList . equals ( _pathList ) ; } }
target:  True if any of the loaded classes have been modified.  If true, the caller should drop the classpath and create a new one.
