Hey Martin!
I've just reviewed your patch, looks good overall.
Here are my thoughts:
* Jenkins CI fails on patch due to missing dependencies,
we need to provide following new dependencies in order
to proceed with the upgrade:
org.aspectj:aspectjweaver:1.8.2
org.aspectj:aspectjrt:1.8.2
com.google.gwt:gwt-user:2.6.1
com.google.gwt:gwt-dev:2.6.1
com.google.gwt:gwt-servlet:2.6.1
com.google.gwt:2.6.1
org.codehaus.mojo:gwt-maven-plugin:2.6.1
com.gwtplatform:gwtp-processors:1.3.1
com.gwtplatform:gwtp-mvp-client:1.3.1
com.google.gwt.inject:gin:2.1.2
Who will take charge of that?
* patch itself looks quite harmless (not too risky)
* consolidating Java source & target version across
frontend and backend is nice!
-> this means we could use Java 7 features
also on the frontend (Java/GWT) side
* TODO-GWT tags [1] proved to be helpful [2]
-> reminder to all UI maintainers to use TODO-GWT
tags whenever we have some GWT(P) workaround,
so that the future upgrade will be safer w.r.t.

PS: I went through GWT-Platform release notes,
found an interesting new feature in recent GWTP
release, worth investigating:

Subject: Moving forward our frontend stack
Hello oVirt developers!
I have prepared patch [1] that upgrades our frontend stack
to use GWT version 2.6.1 (from previous 2.5.1).
This patch also updates GIN to version 2.1.2 and GWT-P to 1.3.1
Since GWT 2.6 features support for Java 7 it was possible to increment
language levels of all projects stuck at Java 6 (common, compat,
searchbackend
and entire of frontend).
To facilitate emitting bytecode compatible with Java 7 also upgrade of
AspectJ was
necessary. This patch upgrades it to AspectJ 1.8 that features even support
for
Java 8 which will save effort when upgrading to GWT 2.7/3.0 in the future.
Most of the changes in the patch are due to upgrade of GWT-P - i.e. changing
packages of TokenFormatter and PlaceRequest.
Overall this patch is *MUCH* simpler than the previous
http://gerrit.ovirt.org/#/c/16739/
which facilitated upgrade from 2.3 to 2.5.1, and hopefully much less risky.
I have tested draft-compile, debug-mode and also tried to use the resulting
application
manually for some time. So far everything worked (surprisingly well!) and I
have not
detected any defects. Of course I invite anyone to test this patch on his own
since
it is and upgrade of our core infrastructure.
That having said I think is comparatively simple and the benefits outweigh
the risks
if this upgrade is done at the beginning of ovirt-3.6 development cycle.
Reviews, comments and testing are very welcome :-)
Best regards,
Martin
