Spring Tool Suite with the Google GWT plugin throws errors in Java2HTMLEntityReader

I tried to update old project to new version of STS. It mostly worked but for some reason, google plugin - required for the project - throws errors:

An error has occurred. See error log for more details.
    org/eclipse/jdt/internal/formatter/comment/Java2HTMLEntityReader

In the error log:

!ENTRY org.eclipse.jface 4 2 2016-03-08 12:39:04.740
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface".

This is caused by the google GWT plug-in. I installed that plugin using STS welcome page button:

So I must have the latest version. I tried to request updates, there are no updates reported for that plugin. I can't step away from GWT at this point, so how can I resolve this problem?

The current version of GPE is broken for mars, meaning this exception occurs. In the not too distant future, this will be fixed.

Until then I have a workaround in a fork that will fix this in mars. Download the fork of the GPE plugin here: http://gwt-plugins.github.io/documentation/gwt-eclipse-plugin/Download.html

Follow the instructions on the download page.
