Potential Solution
One possible explanation for this error, and the loop, is that the
java.security properties file has not been modified to include the
security provider policy file. The installation that reported this problem
added the security provider policy file in the second position within the
java.security file and the problem was resolved. However, you should check
with the vendor for your security provider for detailed installation
instructions.
