​Unfortunately, we've found a bug [1] in GWT 2.8.1 that causes the GWT
debugger (classic dev mode - using Java IDE) to crash right upon startup.

[1] https://github.com/gwtproject/gwt/issues/9522​

The ^^ bug is currently marked as "wontfix" because classic dev mode was
deprecated in GWT 2.8.0 release. For us, classic dev mode remains the only
reliable way to debug our GWT code (even though you have to use a very old
Firefox or Chrome, but it works).

​For​ now, we're going to revert to GWT 2.8.0 so that frontend development
experience isn't affected.
