I got this issue for months after upgrading to Java JRE 7 update 55.
The syndrome is that all java web pages,
including web banks, and even android SDK manager,
cannot be loaded properly after upgrading to the latest JRE.
My working device is using Windows 8, and I think it matters.
And it's difficult to find a solution after copy-pasting the exceptions directly to google!
The exception was too general, leading to lots of useless web pages.
In short, this issue can be solved simply by setting system-wide environment variables
_JPI_VM_OPTIONS=-Djava.net.preferIPv4Stack=true
JAVAWS_VM_ARGS=-Djava.net.preferIPv4Stack=true
Relaunch browsers, and you will see everything works fine again!
As of how to set system-wide environment variables in Win8 is a common system administrator task that can be answered by Google,
or you may refer to the official Java document
http://docs.oracle.com/javase/tutorial/essential/environment/paths.html
Similarly, for running java programs in command line, use
java -Djava.net.preferIPv4Stack=true CLASSNAME
The Android SDK Manager can be treated similarly.
Update tools/android.bat by adding the flag to the latest line so that it looks like
call %java_exe% -Djava.net.preferIPv4Stack=true ...
Then, the GUI interface also works fine :)
