### What changes were proposed in this pull request? There is a race in secure JDBC connection providers. Namely multiple providers can read and/or write the exact same JVM security configuration at the same time. In this PR I've synchronised them with an object class. Since the configuration read and write takes couple of milliseconds it won't cause performance degradation. ### Why are the changes needed? There is a race in secure JDBC connection providers. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Existing unit + integration tests. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
