[PATCH] _java: fix completion when $CLASSPATH contains empty entries

[Mikael Magnusson <mikachu@gmail.com>]

Treat them as a . instead of a / as this is what java does.

jure_ on #zsh noticed that zsh took very long to complete class names, turns out
he had a trailing : in his $CLASSPATH. A quick test shows that java treats these
as a ., not a /, though this does not appear to be documented anywhere.
