cloudadc / cluster Goto Github PK

Current build
mvn clean install -P release
can generate 2 dist

• jbosscache/demo/target/jbosscache-replication-demo-2.0-SNAPSHOT-dist.zip
• build/target/cluster-demo-dist.zip

Now, we need merge these 2 dist as one, which named cluster-demo-dist.zip, under 'build/target/' dir

Issue

JBoss Cluster jGroups Tankwar demo blood not synchronized at the Game beginning

How to reproduce

• Start 2 nodes
• check from both 2 node UI, blood not synchronized

Issue

While start datagrid demo use traditional mood it works fine like below:
java -cp target/dependency/*:target/grid-helloworld.jar -Djava.net.preferIPv4Stack=true com.kylin.infinispan.datagrid.helloworld.Main -c infinispan-distribution.xml

But whem run with jboss-modules-1.1.2.GA.jar, like below:
java -jar jboss-modules-1.1.2.GA.jar -mp -c infinispan-distribution.xml the following exception throw:
Exception in thread "main" org.infinispan.config.ConfigurationException: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[2,208]

How to reproduce?

• infinispan/grid/helloworld-swt have package com.kylin.infinispan.datagrid.helloworld.test.JCD001, which this package contain class can reproduce this issue
• Build the project, more details refer to https://github.com/kylinsoong/cluster/blob/master/how-to-build.asciidoc, this will generate Demo home, set, com.kylin.infinispan.datagrid.helloworld.test.JCD001.JCD001Base DEMO_HOME equal with generated Demo Home
• Run com.kylin.infinispan.datagrid.helloworld.test.JCD001.ModularClassLoadingBoot will throw issue section exception
• Run com.kylin.infinispan.datagrid.helloworld.test.JCD001.TraditionalBoot data grid demo will start correctly

Diagnostic Steps

• Debug Infinispan boot code
• The issue occur while execute org.infinispan.configuration.parsing.ParserRegistry construction method, as below code:

ServiceLoader parsers = ServiceLoader.load(ConfigurationParser.class, cl);
for (ConfigurationParser<?> parser : parsers) {
for (Namespace ns : parser.getSupportedNamespaces()) {
xmlMapper.registerRootElement(new QName(ns.getUri(), ns.getRootElement()), parser);
}
}

while use Modular Class Loading Framework, no element be registered, but use other Class Loading, element be registered

Root Cause

Wrong module.xml dependency cause this issue, boot module depend on grid demo module, grid demo module denpend on infinispan module, the following code:
ServiceLoader parsers = ServiceLoader.load(ConfigurationParser.class, cl);
in infinispan module, but use boot module ModularClassloader, so no ConfigurationParser's implementation be loaded by ServiceLoader load() method

Resolution

Modify boot module module.xml, add infnispan module dependency:
