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)

Vojtech

Subject: [Engine-devel] Does these ERROR will effect WebAdmin build?
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?
Best Regards,
Jason Liao
