How and when do the GWT emulated class work?
I want to know when the GWT Emulated classes from the /emul are invoked overriding the normal java classes. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: GWT Emulated classes
GWT has a feature called "super source" which allows you to override existing source files with your own implementation. GWT itself uses this technique to emulate JRE classes and you can use that technique as well to emulate additional classes. Take a look at http://www.gwtproject.org/doc/latest/DevGuideOrganizingProjects.html#DevGuideModuleXml and scroll a little down until you see the headline "Overriding one package implementation with another" to get a short description of "super source". All JRE classes emulated by GWT can be found in https://github.com/gwtproject/gwt/tree/master/user/super/com/google/gwt/emul and when you look at https://github.com/gwtproject/gwt/blob/master/user/super/com/google/gwt/emul/Emulation.gwt.xml you can see the tag. This tag does not set a path attribute which means that the whole folder which contains the Emulation.gwt.xml file should be treated as super source. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

GWT Emulated classes
I just want to know how does the emulated classes work in GWT. How does the GWT decides where to look for an imported class(inside JDK or emulated classes)? Where is this information is specified? Is there any documentation for this? -- You received this message because you are subscribed to the Google Groups "GWT Users" group.

Re: Errors while updating to GWT2.8.2
Still getting same error. I think instead of getting the String/Object... classes from the jdk, it is trying to look for them in the emulated classes.
