Webdriver not working with Java 1.5

[bpant]

Questions:
Does WebDriver work with Java 1.5? Has it been tested well on Windows
7 64-bit? Is there a detailed compatibility report somewhere, other
than the standard compatibility list of platforms and browsers?

What I see:
Works fine with Java 1.6 (for eg. if I set JAVA_HOME to 1.6 before I
run)

How I build:
JDK compliance set to Java 1.5
JDK used for build: Java 1.6

My test code:
WebDriver browserdriver = new
<thebrowser>Driver();
browserdriver.get("http://inside/");
Thread.sleep(3000);
WebElement elem3 = qeBrowserdriver.findElement(By
.xpath("//html/body"));


I am doing this on:

Windows 7 Enterprise 64-bit
Java : 1.5



Results:

Firefox 3.6.10
=======================================
Hangs, and I get an error like follows:

org.openqa.selenium.firefox.NotConnectedException: Unable to connect

Window remains open, test fails
I have to close the firefox window manually before my test regains
control



Internet Explorer 8
===========================================

Hangs, after a few minutes, I see

I10:17:35:315 .\IEThreadExplorer.cpp(428) Unable to stop IE instance
W10:17:35:315 .\IEThreadExplorer.cpp(432) -2147023174 [The RPC server

Notes: with IE8, I could not get it to work even with Java 1.6, same
error
