SUGGESTED FIX

http://closedjdk.us.oracle.com/jdk8/deploy/deploy/rev/9d8776207321
                                     

EVALUATION

1.  add function to detect if callback is supported by the dt plugin dll.  only call into one arg installLatestJRE if callback is supported.

2.  add fix to replace java.sun.com url with new url (see 7162523 and 7162628)

3.  disable auto-install for IE + 6uX case, because there is a bug now where it's possible to hang.

4.  same fix in (1) need to apply for installJRE also


testcase: http://javaweb.us.oracle.com/~tvng/toolkit/installLatestJRE.html
(try with 6uX and 7uX dt dll)
                                     

EVALUATION

this is because in current deployJava.js:

   installLatestJRE: function(installCallback) {
        if (this.isPluginInstalled()) {
            if (this.getPlugin().installLatestJRE(installCallback)) {
                    ...

In old 6u npdeployjava1 implementation, installLatestJRE checks for zero arg, and return false if it's not zero arg.   That's why we see the problem.
