VERACODE-659,660,663,664: Insufficient Entropy (CWE ID 331)

https://issues.apache.org/jira/browse/CAMEL-7095

During Veracode scan of our application we discover several warnings in Camel. Please review our fix and apply it if it make sense.

Quote from Veracode report below:
Insufficient Entropy (CWE ID 331)(7 flaws)
Description
Standard random number generators do not provide a sufficient amount of entropy when used for security purposes.
Attackers can brute force the output of pseudorandom number generators such as rand().
Effort to Fix: 2 - Implementation error. Fix is approx. 6-50 lines of code. 1 day to fix.
Recommendations
If this random number is used where security is a concern, such as generating a session key or session identifier, use a trusted cryptographic random number generator instead. These can be found on the Windows platform in the
CryptoAPI or in an open source library such as OpenSSL.
