Thorben Bochenek reopened JBRULES-3498:
---------------------------------------

This is indeed a duplicate. However, in 5.4.0.CR1 I can reproduce the error getting the following Stacktracke:

Exception in thread "main" java.lang.NullPointerException
	at org.drools.planner.core.domain.solution.SolutionDescriptor.processPropertyAnnotations(SolutionDescriptor.java:72)
	at org.drools.planner.core.domain.solution.SolutionDescriptor.processAnnotations(SolutionDescriptor.java:64)
	at org.drools.planner.config.solver.SolverConfig.buildSolutionDescriptor(SolverConfig.java:178)

> When the Solution Class has IndexedProperties like "public Day getDay (int dayIndex)" the method processPropertyAnnotations() in SolutionDescriptor will get a NullPointerException on line 71, because for an IndexedPropertyDescriptor getReadMethod() will return null.
