Re: [Engine-devel] Does these ERROR will effect WebAdmin build?

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)
