> Steps to building a new KJar by defining Resource objects and adding then using KieFileSystem.write(), if a Decision Table Template resource type is added then we get a null pointer exception when the KieBuilder.buildAll() method is invoked.
> Sample code that demonstrates this error can be found here: https://github.com/carlmes/decision-table-template, specifically the notes in [TestDecisionTableBuild.java|https://github.com/carlmes/decision-table-template/blob/a68ddd1374f08695fe8d770f0b89bdf76d806e71/src/test/java/test/kjar/build/TestDecisionTableBuild.java#L70].
> Red Hat support case: https://access.redhat.com/support/cases/#/case/02397413
> I have created a proposed fix in [DecisionTableConfigurationImpl.java|https://github.com/kiegroup/drools/blob/f1091fb26d524b99632bad81497e8ad461e9d13f/drools-core/src/main/java/org/drools/core/builder/conf/impl/DecisionTableConfigurationImpl.java#L86], by implementing the missing properties in the fromProperties and toProperties methods. Please see attached updated file that has been tested to fix the issue locally.
