Threads created by other methods use the security settings in the policy file and are not blocked.

A server process is created, use of a Security Manager is enabled, and a "custom.policy" file is generated to be used for all permissions.
The issue faced is that the application fails to function and honor the security settings provided in the "custom.policy"

The following exception is seen.
