Fwd: Tests on Pivot from Java 7

[Sandro Martini <sa...@gmail.com>]

Hi all,
some news on Pivot and JRE 7 (both 64 and 32 bit) on Windows 7 at 64 bit, too ?
Before opening an issue in Oracle I'd prefer to see if someone has
seen the same issue ...

Bye

Hi all,
we are preparing (finally, after many months) release 2.0.1 ... so
this week I started to do many tests, generating all things from
latest sources (from trunk), BUT yesterday I found a strange thing
with JRE 7:

I generate both war files from latest Pivot sources, and deployed in a
local Tomcat 6.0.30, and then even in 6.0.33 .
Then, from any browser (Firefox 6, Internet Explorer 9 at 32 and at 64
bit) anytime I try to run an Applet (and even a Web Start application
!!) the download of jars start, but never ends ... very strange, and I
don't think related to our code, but to something in the JRE 7.
In the Java Console I have tried even to get the maximum level of
info, raising to level 5, and reloading confgiuration and page, but
the same ...
This is my console log (this is when I try to get things from
localhost, but with the url to my real hostname is the same):

seem that something is waiting on the last line ...

In Internet Explorer 9 @ 64 bit, I use the folloqing VM, but the story
is the same ...
Uso della versione JRE 1.7.0-b147 Java HotSpot(TM) 64-Bit Server VM

But loading pages from the local filesystem (for example via dragging
them in a browser) all works, this is the console log:

It seem really something related to network and/or http ...


Last , tried to copy unpacked files even in a Apache http server
2.2.x, and tried to get all from it, via http ... same results.


But to make things more complex, some Applets on Internet were
successfully loaded and running on my system (like the Test on
java.com, some applet from "The java Tutorial", and even sono of our
demos and tutorials applets on http://pivot.apache.org/ ).


My primary development system, has Windows 7 at 64 bit, with installed
latest JDK 6 Update 26 at 64 bit, JRE 6 U 26 at 64 bit, and Java 6 U
26 at 32 bit.
Then I installed even JDK 7 at 64 bit, JRE 7 at 64 bit, and JRE 7 at
32 bit ... just to have everything installed, and in the same order.
So I can test anything in 64 bit environment and in 32 environment.

This evening I tried from some VM (getting files via http, from the
external host, the Windows 7 at 64 bit seen before) but with Windows 7
at 32 bit and Win XP at 32 bit, and all here works good ... and here
installed I have JRE 6 U 27 and JRE 7, both at 32 bit of course.


And in other platforms, someone has tried ?

If someone have ideas ... or is someone is able to try, so we can see
if it's a common behavior.
Today I looked in Oracle (bugs , forums, etc) but I found nothing like this.

If it's a real JRE bug I'll open as soon as possible a ticket in
Oracle, but I hope to not be the only to have this strange thing ...
or if yes better (=no common bug :-) ).

Bye,
Sandro

Hi,
this is the issue at Oracle:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7087149

I'm in contact with Oracle to see if/how to solve this, as soon as possible.

A quick troubleshooting guide here:
http://download.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/plugin.html


A friend told me that a workaround could be to try to pass this flag:
-Djava.net.preferIPv4Stack=true
to the JVM in case of this error (but haven't tried), so report here just to
have more data.


Bye
