Java Plugin (Plugin2) does not evaluate automatic proxy files correctly
on Linux platforms. It appears as if the first proxy listed in function
FindProxyForURL() is used, regardless if it is guarded by a condition.
The behavior is strictly reproducible and requires, that an automatic
proxy file is configured in the Java Control Panel.
The behavior is not reproducible on Windows platforms.
The behavior is independent from the browser version and how the browser
is configured proxy-wise.
