jmeter.threads.JMeterThread: Test failed! java.lang.OutOfMemoryError: Java

Typically 1 virtual user is equivalent to 150 real users.

Also note that 1 virtual user can generate more load than a single
real user. Real users tend to wait between clicking links, JMeter does
not have to.
Try to establish what load your server is supposed to handle, and then
see how to generate that load using JMeter.
There are some useful testing links on the Wiki.

Also note that 1 virtual user can generate more load than a single

You have to consider that 1VU = 1 Thread in JMeter. It's quite over the
boundaries for a single PC to manage millions threads. I'd suggest using
remote testing feature.

That's far too many users for one machine to handle. I find I'm pushing
what my workstation can handle with 100 users, but I'm doing a test
that's fairly hard on JMeter.
If you really want to run that many threads, you'll need a lot of memory
- try allowing JMeter to use all of your memory (this had better be
several Gb). And try starting at 1000 or less...
Also, I'd recommend using something other than Windows to run JMeter (if
you're not already), as in my experience, Windows doesn't handle that
many active threads very well...
That probably wasn't what you wanted to hear, but I hope it helps...
