The bug
I filed a bug report to Sun after I was very surprised to find it had not already been filed, years ago. I got a response from a Sun engineer named Jitender:
“I tried this but could not reproduce the momentary freeze you have mentioned. It seems it could be related to RAM also. Even more RAM requirements are mentioned in JDK 5.0 Installation notes available at http://java.sun.com/j2se/1.5.0/install-windows.html”
I have 512MB RAM, a 1.8Ghz P4-M, and a 5200RPM disk. Visiting a Java applet locks up for about 10 seconds the first time I visit. It happens to my friends, in IE and in Firefox, on Windows and Linux. I think it’s obviously not “not reproducible.”
Help get this fixed
So, tell me - when you visit a page with a Java applet, does your web browser completely lock up for a few seconds? If you’re not sure, visit this calculator applet and count how long your browser is unresponsive. If you notice any freeze, please leave a comment below with your system specs (memory, CPU, disk speed if possible) and how long it froze for.
Your results will be most useful if you make sure all Java programs on your computer are closed, so we get a “cold start” time. It would be even better if you restart your computer and don’t run any Java programs before visiting the above web site. However, any results will help!
I will forward your list of lock-up times and system configurations to Sun, so maybe they will believe me. I think fixing this problem would be a huge step towards Java being more accepted on the desktop.
UPDATE: The bug was filed as Bug 6267809 and was quickly marked “Closed, not a bug.” You should post your lockup times as comments to that bug, instead of here. I have posted all previous comments here as comments on the bug as well.
