Warning with JAVA 24 / 25 - Call to deprecated method

Thanks for reporting. It will be fixed for the next release.

Thank you. I will check this later.

It all depends on multiple factors, including the transaction model, how you use database connections and when you commit. Each thread must always use a separate connection to write to the database. In the default LOCKS mode, if multiple threads write to the same table, then the first thread's connection needs to be committed before any other thread can write. In the MVCC mode multiple connections can generally write without committing so long as there is no conflict.

Reused statement invalidated

Thanks for reporting. Please note there have been a lot of changes since version 2.5.2. Please check with version 2.7.4 (either Java 8 or Java 11 jar).

Thanks for reporting. Will check it later.

Regression in 2.7.4 with respect to auto-generated keys in prepared statements
