GWT Google Material Design out of memory
I created a wesbite with GWT 2.8.1 and try to use GMT. I followed Getting Started from the GMT demo website but without using the archetype. This is my pom:

</build>
and this is my .gwt.xml:
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='SampleModule'>
<inherits name='com.google.gwt.user.User'/>
<!--<inherits name='com.google.gwt.user.theme.standard.Standard'/>-->
<inherits name="gwt.material.design.GwtMaterialDesign"/>
<entry-point class='de.sample.sampleproject.client.SampleModule'/>
<source path='client'/>
<source path='shared'/>
</module>
If I run this and start the browser (Opera in my case, but tried FF and Edge too), it runs into an out of memory. If I inherit com.google.gwt.user.theme.standard.Standard instead of gwt.material.design.GwtMaterialDesign, the app runs fine.
I compared my pom with the one from the GMT archetype and the main differences are the additional plugins like GIN, GWTP and so on. Does GMT have a dependency on these or am I missing something else?
Edit
This is the console output, before and after the browsers OOM:

As you can see in the image, Chrome is running a lot longer than opera. It crashes after more than 2GB.
Solution
Found a solution but not the reason.
As I meantioned in the comments of the question, I used the quickstart archetype. I did not changed anything in my pom but in the .gwt.xml:
<?xml version="1.0" encoding="UTF-8"?>
<module rename-to='SampleModule'>
<inherits name='com.google.gwt.user.User'/>
<!-- DOES NOT WORK -->
<!--<inherits name="gwt.material.design.GwtMaterialDesign"/>-->
<!-- One of the following DOES work -->
<!--<inherits name="gwt.material.design.GwtMaterialDesign"/>-->
<inherits name="gwt.material.design.GwtMaterialBasicWithJQuery"/>
<entry-point class='de.sample.sampleproject.client.SampleModule'/>
<source path='client'/>
<source path='shared'/>
</module>
Even that I did not use any of the GMT elements or styles, I have to load JQuery. So I guess it does rely on it. Unfortunately this is not mentioned in the docs. I always thought JQuery is optional.
