A simple deployment that uses a known layers configuration to provide a trimmed server that is capable of cache distribution.
<layers>
<layer>jaxrs-server</layer>
<layer>web-clustering</layer>
<layer>ejb</layer>
<layer>ejb-dist-cache</layer>
</layers>
<excluded-layers>
<layer>ejb-local-cache</layer>
</excluded-layers>
is built successfully but then throws an NPE at startup:
15:35:32,735 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 60) MSC000001: Failed to start service org.wildfly.clustering.jgroups.channel.ee: org.jboss.msc.service.StartException in service org.wildfly.clustering.jgroups.channel.ee: java.lang.IllegalStateException: java.lang.NullPointerException at org.wildfly.clustering.service@27.0.0.Final-SNAPSHOT//org.wildfly.clustering.service.FunctionalService.start(FunctionalService.java:66)
This happens when using the WildFly 27.0.0.Final-SNAPSHOT and wildfly-cloud-galleon-pack v. 2.0.0.Beta2.
The stack trace leads to a call [1] that looks for a socket binding which actually is not set for FD_SOCK and FD_SOCK2 in the generated server standalone.xml:
