Sanne Grinovero ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HHH-16903 ( https://hibernate.atlassian.net/browse/HHH-16903?atlOrigin=eyJpIjoiOGEyM2... ) Re: java.lang.IllegalStateException: Illegal pop() with non-matching JdbcValuesSourceProcessingState ( https://hibernate.atlassian.net/browse/HHH-16903?atlOrigin=eyJpIjoiOGEyM2... ) It looks like you’re running operations in parallel via “supplyAsync” - that will lead to multithreaded and/or out of order operations to be scheduled, and will certainly lead to problems: please don’t do it. I’m wondering if I should close this issue, or if we can find some way to detect such mistakes. Perhaps https://hibernate.atlassian.net/browse/HHH-16869 could be enough.
