Re: AccessControlException with no security manager
Probably best to open an issue in the Derby JIRA, to help keep the conversation easy to find and track. Can you share the complete stack trace of the AccessControlException? Can you share a run of 'sysinfo' in a configuration where this occurs? I don't suppose you've been able to whittle this down to a Minimum Reproducible Case yet, have you? thanks, bryan On Thu, Jun 6, 2019 at 6:22 AM Besosa, Michael wrote: > > We're still interested in ideas about this problem.

Re: AccessControlException with no security manager
We're still interested in ideas about this problem. We are getting occasional AccessControlExceptions in an environment with no SecurityManager installed. This behavior appears to have started when we migrated our application to Java 8. It was never seen prior to that. If there is additional information that would be useful, please let me know.
