Hi everyone,

yesterday, we merged https://gerrit.ovirt.org/#/c/75705/ which seals Engine query & action result classes.

We will follow this up with renaming "VdcReturnValueBase" to "ActionReturnValue" and doing similar renames to existing "VdcSomething" classes.

The reason for finalizing those result classes is to avoid us implementing a GWT custom field serializer for each such subclass, therefore limiting our exposure to GWT RPC specifics when transferring objects between client and server.

On a side note, we also upgraded GWT 2.8.0 to 2.8.1 which fixes a GWT compiler bug we had to work around: https://gerrit.ovirt.org/#/c/77264/

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.

Vojtech
