Re: [Subclipse-dev] Excessive use of TCP sockets

I do not know if it is causing these TCP connection time outs, but I
talked to the SVN developers and we should be calling the dispose()
method.

The change I am looking into is to only ever create a single
JhlClientAdapter object ... then we would not need to call this
method.

I never understood why it did not work this way already.
