Adding Security Provider multiple times in Java application

Question

We have a Java application where a job is scheduled to run every 5 minutes. In that job, there is a security component that does the following every time it is executed:

java.security.Security
            .addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

My questions are:

1. Is it required to add the security provider multiple times in the application? Does it serve any purpose? To me, it doesn't make sense and adding it once should suffice.
2. Is it a candidate for a potential memory leak in the application?

To clarify, I want to add Bouncy Castle security provider programmatically in my application and not statically via JRE. IMO, adding Bouncy Castle security provider once in the application is enough and I need not do in multiple times.
