JIRA: https://jira.springsource.org/browse/INT-3252 Remove the use of `SecureRandom.generateSeed()` which is not supported on some platforms. Note: While this change does not reflect the custom IBM code noted in the JIRA issue, it does revert the initial SecureRandom generation to use the same code as UUID.randomUUID(), so the expectation is that this will work fine on zOS.
