Description Sebastian Haas 2020-09-17 08:16:26 UTC
The inner class org.apache.tomcat.dbcp.dbcp2.BasicDataSource$PaGetConnection was removed in 9.0.38, but the class is still loaded in the static initialization block when the SecurityManager is activated.

The problematic code also exists upstream in the Apache Commons DBCP project.
I haven't reported it there yet.
