3.0.0.Alpha4 breaks DeltaSpike 1.2.1

[juergen.zimmermann]

I'm using the latest snapshot of WildFly 9.2.0 and applied the patch for Weld (in the ZIP file I edited patch.xml and changed the WildFly version number to 9.0.0.Alpha2-SNAPSHOT). When I deploy my WAR which contains DeltaSpike I get the following stacktrace. Is this a failure of DeltaSpike (see hints below) or of Weld?

ERROR [org.jboss.msc.service.fail] MSC000001: Failed to start service jboss.deployment.unit."shop.war".WeldStartService: org.jboss.msc.service.StartException in service jboss.deployment.unit."shop.war".WeldStartService: Failed to start service

This is the relevant part of DeltaSpike's ExceptionUtil:

@Typed()

public abstract class ExceptionUtils

{

    private ExceptionUtils()

    {

        // prevent instantiation

    }

The inner class ExceptionUtils.ExceptionHelper is "private static" and has just 1 private method.

Weld Probe is causing the problem. When I change the context parameter (in web.xml) org.jboss.weld.development to false, then the issue is gone.

Hi Juergen,

thanks for reporting. This is a known issue. We have fixed the detection of unproxyable types in this commit (https://github.com/weld/core/pull/852, not merged in master yet). There is another workaround (aside from disabling the dev mode) - exclude the deltaspike types from monitoring via org.jboss.weld.probe.invocationMonitorExclude Weld configuration property. E.g. place a weld.properties file which contains a line org.jboss.weld.probe.invocationMonitorExclude=.*deltaspike.* in WEB-INF/classes.  However, this key only works for  3.0.0.Alpha4, in the next Alpha this property will have a slightly different key.

I created weld.properties with this line because PicketLink classes also caused problems:
org.jboss.weld.probe.invocationMonitorExclude = .*deltaspike.* .*picketlink.*

But now I'm getting again a stacktrace because of DeltaSpike:

Try org.jboss.weld.probe.invocationMonitorExclude = .*deltaspike.*|.*picketlink.* instead. You can use http://www.ocpsoft.org/tutorials/regular-expressions/java-visual-regex-tester/ to test the regex.

Thank you, Martin. Weld Probe is working fine!

I'm glad it's working! Note that for the next release (Alpha5) this shouldn't be necessary. Also this property will have a slightly different key and there will be other "exclude" possibilities, e.g. to allow to skip JavaBean accessor methods.
