Christopher Schultz updated VELOCITY-968:
-----------------------------------------
Description:
When running under Java 17 or later, introspection often picks an inaccessible
method on a runtime object, which then fails when invoked.
For example, running the example below under Java 8, the output is simple:
{noformat}
Cert notAfter=Wed Jan 03 12:42:32 EST 2024
Test: Wed Jan 03 12:42:32 EST 2024
{noformat}
When running on Java 11 or later, we get:
{noformat}
Cert notAfter=Wed Jan 03 12:42:32 EST 2024

It looks like Velocity is picking an inconvenient class on which to base its
method invocation.
Here is the test source.
