Typing the name of a new class in the New Java Class dialog is slow using ftp. If I do this using ssh/dstore it runs very smoothly. Looking at the Console log it looks like we are doing a CWD & LIST command for every character typed. Steps to Reproduce: 1. Create a Java Project. 2. Remove the source folder. 3. Create a new folder linked to an ftp system. 4. Make the new folder a source folder. 5. Right click on the folder. Select New -> Class. 6. Type in the name of a class. The name will slowly appear.

Looking at the log, there are indeed directory list queries of the same directory in quick succession. Looking at the code in FTPService.java, we should be caching the result of a previous FTP LIST query and re-use it when the next query is the same and not too much time has passed. Javier can you check why this caching fails?
