Issue/Introduction
When writing GemFire client code that uses PDX serialization, do NOT use immutable collections as these will cause PDX serialization to fail.
Environment
Product Version: Other
Resolution
GemFire PDX serialization doesn't support immutable collections such as those introduced in Java 9 with factory methods like List.of(), Map.of(), Set.of() that create an immutable instances.
If you use one of these methods to create a domain object instance that will be stored in GemFire, PDX serialization will fail during the put operation. Instead, you should use something like ArrayList which creates a non-immutable collection instead.
