Slair1 opened a new issue #3826: Unsafe Field Accessor with newer mysql-connector-java package URL: https://github.com/apache/cloudstack/issues/3826 <!-- Verify first that your issue/request is not already reported on GitHub. Also test if the latest release and master branch are affected too. Always add information AFTER of these HTML comments, but no need to delete the comments. --> ##### ISSUE TYPE <!-- Pick one below and delete the rest --> * Bug Report ##### COMPONENT NAME <!-- Categorize the issue, e.g. API, VR, VPN, UI, etc. --> ~~~ mysql-connector-java ~~~ ##### CLOUDSTACK VERSION <!-- New line separated list of affected versions, commit ID for issues on master branch. --> ~~~ 4.11.3 all ~~~ ##### CONFIGURATION <!-- Information about the configuration if relevant, e.g. basic network, advanced networking, etc. N/A otherwise --> ##### OS / ENVIRONMENT <!-- Information about the environment if relevant, N/A otherwise --> CentOS7 ##### SUMMARY <!-- Explain the problem/feature briefly --> Looks like the new version (8.0.x) is stricter with conversions from Long to BigIntfor example. Auto Increment fields in the database are of type BigInt, but in code we are using Long. This generates the errors similar to the following at times: ~~~ Can not set long field com.cloud.upgrade.dao.VersionVO.id to java.math.BigInteger ~~~ ##### STEPS TO REPRODUCE <!-- For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate. For new features, show how the feature would be used. --> Install any new version of mysql-connector-java <!-- Paste example playbooks or commands between quotes below --> ~~~ We hit it while the database upgrade script was running 4.9.3.0 -> 4.10.0 ~~~ <!-- You can also paste gist.github.com links for larger files --> ##### EXPECTED RESULTS <!-- What did you expect to happen when running the steps above? --> ~~~ Looks like older versions of mysql-connector-java did not care that we use Long in code by BigInt in the database columns ~~~ ##### ACTUAL RESULTS <!-- What actually happened? --> We get errors such as this: <!-- Paste verbatim command output between quotes below --> ~~~ Caused by: java.lang.IllegalArgumentException: Can not set long field com.cloud.upgrade.dao.VersionVO.id to java.math.BigInteger at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:167) at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:171) at sun.reflect.UnsafeLongFieldAccessorImpl.set(UnsafeLongFieldAccessorImpl.java:102) ~~~
