There is a reproducer example attached. Here's what the issue description is:
When enabling the karaf.lock option, the bundle explicitly using Saxon as XPathFactory fail to start when JBoss Fuse is starting.
- Referring to this doc about JDBC locking, https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Fuse/6.2.1/html/Configuring_and_Running_JBoss_Fuse/ESBRuntimeFailoverJdbc.html, have the following in the /etc/system.properties file,
karaf.lock.level=100 karaf.lock=true karaf.lock.class=org.apache.karaf.main.MySQLJDBCLock karaf.lock.jdbc.url=jdbc:mysql://127.0.0.1:3306/test karaf.lock.jdbc.driver=com.mysql.jdbc.Driver karaf.lock.jdbc.user=root karaf.lock.jdbc.password= karaf.lock.jdbc.table=KARAF_LOCK karaf.lock.jdbc.clustername=karaf karaf.lock.jdbc.timeout=30
Then have the below entry in the /bin/karaf script:
# Add the jars in the lib dir
for file in "$KARAF_HOME"/lib/karaf*.jar
do
if [ -z "$CLASSPATH" ]; then
CLASSPATH="$file"
else
CLASSPATH="$CLASSPATH:$file"
fi
done
CLASSPATH="$CLASSPATH:$KARAF_HOME/lib/mysql-connector-java-5.0.8-bin.jar"
- First, my Fuse server instance and already running and the bundle is already deployed. I then modify the system.properties with the karaf.lock.level=100 entry and i do not see any issues.
- Next, i then uninstall the bundle. I install the bundle again, but can't see any issues.
- Then i do a 'dev:restart' of Fuse, with the bundle deployed and i can see the ERROR message on the logs.
- After that, if i simply do a refresh <bundle-id>, the problem goes away.
Below is the error message i can see:
15:11:54,030 | ERROR | FelixStartLevel | BlueprintCamelContext | 234 - org.apache.camel.camel-blueprint - 2.17.0.redhat-630254 | Error occurred during starting Camel: CamelContext(saxon-test) due No XPathFctory implementation found for the object model: http://saxon.sf.net/jaxp/xpath/om javax.xml.xpath.XPathFactoryConfigurationException: No XPathFctory implementation found for the object model: http://saxon.sf.net/jaxp/xpath/om at javax.xml.xpath.XPathFactory.newInstance(Unknown Source)[:2.7.0]
Also, customer reports that if we set the start-level for all bundles using XPath to a value > lock-level everything works as expected. I believe a manual intervention should not be required for this to load after Fuse has been restarted.
