Re: Firefox in OS X freezes in DevMode.

Line 155:

ssize_t n = recv(sock, readBuf, BUF_SIZE, 0);

That seems to say 'block until bytes are written by the other end of the socket', or in other words, wait until the JVM is ready to go. Are you sure that the IDE isn't paused on a breakpoint, or that you have waited long enough for the page to load? When the browser is in this state, try pausing the JVM to see what the dev mode thread is doing - I'm betting it is hard at work on something... but if it too is waiting for something, that could be a problem.

But the recv call is *supposed* to block, at least until dev mode has finished running its not-yet-JS code.

We've had no issues with Mavericks and latest FF in our projects fwiw, aside from the usual 'dev mode takes longer to do anything' fun.

I'm started to have issues when trying to use DevMode with Firefox in OS X and the only thing "new" is that I upgraded to Mavericks.

Here's what I see: I create a GWT sample app (the default one that comes with the Eclipse GWT plugin), I launch dev mode and try to access it with Firefox, as soon as I paste the address, the browser freezes.

It stays frozen until I stop development mode, once I do that, Firefox comes back to life.

Using Chrome is fine. I also have a VM setup with Linux and Firefox, if I try to debug through that Firefox, everything works as well.

I tried to see if there was any sort of deadlock in the devmode plugin by using jconsole but it says that there's no deadlock.

I have already ensured that Firefox is clean by doing a "Reset Firefox...".

Apparently the only thing that fixes this issue is by creating a new profile. After I create a new profile, I only install the GWT plugin and works for a few days, then it freezes again. I don't install anything else in Firefox.

I have tried different versions of Firefox (21, 24 and 25) and I see the same behavior in all of them.

I was wondering if anyone else could be seeing something similar and/or would have any suggestions as to how to debug the GWT extension to try to figure out what's going on?
