Environment Details

  • EclipseStore Version: 2.1.1
  • JDK version: 22
  • OS: MacOS
  • Used frameworks: Helidon

Describe the bug

I store an object with this inside:

private final ConcurrentSkipListMap<InstantRange, Lazy<List<AuditEvent>>> eventsByPeriod = new ConcurrentSkipListMap<>(new Range.Comparator<>());

But the comparator in the constructor is not stored, so it remains NULL upon loading the map. This causes nasty run-time errors (in my case weeks after deployment!), because without the backing comparator, the key is expected to be Comparable:

 java.lang.ClassCastException: class com.utilities.InstantRange cannot be cast to class java.lang.Comparable

May closely related or identical to #352.
At first glance the comperator seems not jet being loaded when the binary handler instantiates the ConcurrentSkipListSet / Map in the create method. Thus it instantiates with null instead of an comparator instance.
