> Credential store handling has a one-way logic to move passwords to jceks files and then
removing the passwords from the configs. When agent does an auto-retry of command execution
then the initial assumption of relying on the existence of the "password" properties no longer
holds true. This incorrectly disables credential store but as passwords are no longer available
it results in broken configurations.
> The solution here is to avoid processing the password properties when command is an implicit
retry.
