Description
error calling Constructor for org.javers.core.metamodel.type.CustomType exception is thrown on javers.compare(..) when there is a CustomPropertyComparator registered for a parent class of some value that exist in objects that are being compared.
Here is a test case that reproduces the issue: https://github.com/kkonstantin42/javers/blob/custom-property-comparator-with-inheritance/javers-core/src/test/groovy/org/javers/core/cases/CustomPropertyComparatorWithInheritanceCase.groovy
This behaviour has appeared after CustomType constructor was changed to accept CustomPropertyComparator as a second parameter in this commit: ec6113b#diff-461b37401e91dc6db100811e06995807
Possibly there should be a special case in TypeFactory.spawnFromPrototype method that would handle creation of CustomType objects. Can submit a PR.
Here is a stacktrace:
