So I noticed a difference in deploying the exact same kar in the new karaf
4.3.0.RC1 version and the older ones. When I try to install a kar with the
feature (simplified) found below with the mariadb JDBC driver it throws a
nullpointer exception with stacktrace found down below.
But what I find odd is that this kar installs without problems on earlier
Karaf versions. What is furthermore odd is that only putting the mariadb
bundle in deploy works perfectly fine in both versions.
Anyone any idea what is causing this odd behaviour and if it's a bug of the
karaf 4.3.0.RC1 version?
Feature:
<feature name="mariadb" version="${project.version}">
<bundle>mvn:org.mariadb.jdbc/mariadb-java-client/${mariadb.client.version}</bundle>
</feature>
Stacktrace:
java.lang.NullPointerException: null
