Description Martin Oberhuber CLA 2007-08-02 08:34:32 EDT 
From bug 192610 comment 19 ff:

There may be issues with Eclipse / EFS keeping multiple streams to the remote open in multiple threads -- it could totally hang ftp connections and make other connection types unusable while the streams are still open.

Best would be writing a JUnit test for the scenario mentioned. This could be pretty simple:
  * Get FTPService instance from RSE
  * Create 2 directories, upload 4 files
  * In 4 different threads, getInputStream() and start downloading but do not
    close the streams yet
  * Try performing some list/chdir commands
  * Close the 4 streams one after another with more list/chdir commands
    interspersed

Having such a unit test would be fabulous, and should be applied to the SSH (Sftp) case as well. In fact, such a unit test would be the most important to protect against regressions with the EFS integration.

There is a general, conceptual issue with multiple concurrently open streams to remote resources at the same time.

I have filed bug 198683 to discuss this in a generic (EFS) context.
