Re: compilerArgs setProperty multi values - [ERROR] Unable to parse JavaScript

I would say that you're not supposed to set compiler.stackMode to anything but a single value, because it doesn't have a property-provider; and that's exactly the problem with the generated JS: the snippet where the error occurs is a property provider, but because there's no <property-provider> for that property, it generates invalid JS (granted, it could have failed instead).

What I don't quite understand is that you're saying (IIUC) it only occurs with -setProperty and not <set-property>.

Hi,

On a GWT 2.8.2 Maven project using tbroyer/gwt-maven-plugin

When I declare:

<compilerArgs>
  <arg>-setProperty</arg>
  <arg>compiler.stackMode=native,emulated</arg>
</compilerArgs>

it fails:
