Issue

1. Normal/enterprise version fails with alignmentKey in SubTask.java#101

 java.lang.IllegalArgumentException: There are fixed dependency loops in the graph for variables

2. Enterprise version without ASSERT in solverConfig

 java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 45
