Hi,
(CC'ing Juan, please feel free to correct/add to my comments.)
I think that ERRORs such as:
[ERROR] [AppClassLoader@...] ... [ERROR] [GinBridgeClassLoader@...] ...
come from AspectJ load-time weaver [1] logging its output to stderr.
[1] GWT compilation includes JVM args: -javaagent:/path/to/aspectjweaver-${aspectj.version}.jar
We use AspectJ [2] to prevent GWT compiler from optimizing-out code in backend business entities, i.e. some code in business entities is not used on client and GWT compiler thinks its dead code, but when it's optimized-out we would face serialization errors on server.
[2] frontend/webadmin/modules/gwt-extension/ src/main/java/org/ovirt/engine/ui/gwtextension/DontPrune.java
So these kinds of ERRORs are harmless.
The other ERRORs such as:
[ERROR] ... java.util.prefs.FileSystemPreferences$1 run [ERROR] INFO: Created user preferences directory.
come from Java's "Preferences" subsystem, as we override default preference file locations [3] in order to avoid conflicts when running multiple JVMs at once, i.e. parallel Engine build.
[3] GWT compilation includes JVM args: -Djava.io.tmpdir="${project.build.directory}/tmp" -Djava.util.prefs.systemRoot="${project.build.directory}/tmp/.java" -Djava.util.prefs.userRoot="${project.build.directory}/tmp/.java"
Also these kinds of ERRORs are harmless.
So for now, you can safely ignore these ERRORs.
To me, it seems that when gwt-maven-plugin:compile goal executes, it spawns new JVM (invoking GWT compiler) and *redirects* stdout of this JVM to plugin logger's stderr.
Juan, what are your thoughts? (maybe I'm missing something)
You are right Vojtech, those error messages are harmless.

Hi All,
When I build the WebAdmin from development mode on oVirt engine, I meet these ERROR message:

Build seems that the oVirt engine could work well after the build,
does anybody know these errors maybe effect something, and how to prevent them from maven build log?
