Subject: [PATCH 1/3] Update pom.xml

Using the latest stable release Apache Jackrabbit 2.22.x (Java 11 and later), I am trying to run example FirstHop.java and it failed with several errors. Including JDK version, which was given as 1.5 in the pom before, missing dependency for jackrabbit-jcr-commons.
Another Problem was Derby 10.15.2.0 had EmbeddedDriver class location changes which resulted in javax.jcr.RepositoryException: Cannot instantiate persistence manager org.apache.jackrabbit.core.persistence.pool.DerbyPersistenceManager
Caused by: java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver
Made changes to pom.xml file to Derby 10.14.2.0 for compatibility reasons.
