When I enable Closure Compiler and set GWT JavaScript compiler output style to DETAILED mode
by providing the following configuration of gwt-maven-plugin:
<configuration>
<modules>
<module>org.eclipse.che.ide.IDE</module>
</modules>
<style>DETAILED</style>
<enableClosureCompiler>true</enableClosureCompiler>
</configuration>
I get the following compilation error:

It means that using 'arguments' as a name of a method parameter is forbidden by Google Closure Compiler because, it seems, that it's reserved for internal using here:
