I'm following the instructions in readme file to set up a simple project. But JVM filed to initialize. From network log, the last file loaded was rt.jar. All files have been downloaded successfully.

Please provide your scripts, etc. so we can try to reproduce. Thanks.

@emeryberger I created a simple project to show this error.

git clone [email protected]:haitaoli/doppio-demo.git
cd doppio-demo
npm i
npm start

@haitaoli You need to use BrowserFS version 1.2. (Newer versions past 1.2 work if you install BrowserFS's spec-incompatible setImmediate polyfill: window.setImmediate = BrowserFS.setImmediate)
