you can see following code
'connection.setDefaultUsesCaches(false)'.
the variable 'connection' is instance of HttpUrlConnection.
so, calling this makes following all new URLConnection disable cache.

this is critical if when it's in applet code.
whenever we access to resources inside jar using 'jar://' protocol,
network connection will made.

make a applet that uses IPP connection.
after getting IPPConnetion, all 'jar://' url connection make re-downloading of jar.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
using a printer should not affect class loading or other URLConnection
