Hi there,

I just switched to 2.8 on a major GWT project. I am using Eclipse on MacOS.

As soon as I start running the application, I get a 

java.lang.OutOfMemoryError: unable to create new native thread

I had a look at the threads using jProfiler and saw that the number of threads during startup increased very quickly.

GWT seems to create a Thread for each file that needs to be "monitored".
As soon as I turn off "watchFileChanges", the application starts in SDM properly.

I managed to get it working by setting


in the command line.

It has been on a thread before: https://groups.google.com/d/msg/Google-Web-Toolkit-Contributors/3skc7sbbp2g/EQrbUP79CgAJ

It works without "watchFileChanges", but what does it mean for development?
