IcedTea Java plugin cannot load applet jar file

[Jiri Vanek]

hi!

In next release of 1.4 (current stable)  will be console enabled and *show-able* . It is enabled 
since 1.3, however by error it was never visible.
if interested, you may see this simple patch : 
http://icedtea.classpath.org/hg/release/icedtea-web-1.4/rev/acbada276d23 , which had fixed it.

For 1.5 the console is going to be completely rewritten - see 
http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2013-November/025342.html if you wont to 
affect its development :)

Best regards
   J.
