Use concurrent cache to improve performance of GenericTypeResolver [SPR-8701]

[spring-projects-issues]

Oliver Drotbohm opened SPR-8701 and commented

Working with Spring Data Mongo a user seems to have discovered a few things to improve in GenericTypeResolver. We're currently using a copy of that class in the Spring Data codebase as some of the methods needed are not public in the 3.0.x branch. I thought it might be better to generally discuss and resolve these issues with the core Spring class as we will drop our copy as soon as 3.1 is out as well and Spring users might benefit from potential improvements in general.

Actual discussion in the linked ticket.

Oliver Drotbohm There is now a new ConcurrentReferenceHashMap class that should provide much better concurrent performance whilst still supporting weak keys and values. Any time you have to review the changes would be must appreciated.
