[JBoss JIRA] (WFLY-3067) Annotations from .ear/lib are not visible to DUPs when processing subdeployments
by Kyle Lape (JIRA)
Kyle Lape created WFLY-3067:
-------------------------------
Summary: Annotations from .ear/lib are not visible to DUPs when processing subdeployments
Key: WFLY-3067
URL: https://issues.jboss.org/browse/WFLY-3067
Project: WildFly
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Class Loading
Affects Versions: 8.0.0.Final
Reporter: Kyle Lape
Assignee: David Lloyd
Sample use case: You have a .war in an .ear, and the .war has a web.xml with a {{<servlet-class>}} that refers to a JAX-WS endpoint, so the class is annotated with {{@WebService}}. If that class is packaged in a jar found in the ear's lib directory, the JBossWS DUP won't pick it up, and then Undertow will throw an error like this:
{noformat}
UT010009: Servlet ClientEndpoint of type class com.redhat.gss.jaxws.ClientEndpoint does not implement javax.servlet.Servlet
{noformat}

[JBoss JIRA] (JGRP-1805) OverlappingMergeTest testMergeWithDifferentPartitions fails to create correct merged view
by Richard Achmatowicz (JIRA)

-----------------------------------------
Summary: OverlappingMergeTest testMergeWithDifferentPartitions fails to create correct merged view
Key: JGRP-1805
URL: https://issues.jboss.org/browse/JGRP-1805
Project: JGroups
Issue Type: Bug
Affects Versions: 3.2.13
Environment: RHEL
Reporter: Richard Achmatowicz
Assignee: Bela Ban
Fix For: 3.2.13
This test does the following:
- creates four channels a,b,c,d
- injects views A: {A,C,B}, B:{A,C,B}, C:{A,C,B} and D: {B,A,C,D}
- injects a merge event in each of channels A,B,C,D representing these four views
- checks that all channels have the final view of size 4
The test fails intermittently on RHEL, with the same failure each time:

[JBoss JIRA] (JGRP-1805) OverlappingMergeTest testMergeWithDifferentPartitions fails to create correct merged view
by Richard Achmatowicz (JIRA)
[ https://issues.jboss.org/browse/JGRP-1805?page=com.atlassian.jira.plugin.... ]
Richard Achmatowicz updated JGRP-1805:
--------------------------------------
Description:
This test does the following:
- creates four channels a,b,c,d
- injects views A: {A,C,B}, B:{A,C,B}, C:{A,C,B} and D: {B,A,C,D}
- injects a merge event in each of channels A,B,C,D representing these four views
- checks that all channels have the final view of size 4
The test fails intermittently on RHEL, with the same failure each time:
