OutOfMemoryError BouncyCastleProvider.addAlgorithm

[crescent7272]

I have an OOM problem. This is the stacktrace on Firebase Crashlytics.

Fatal Exception: java.lang.OutOfMemoryError: Failed to allocate a 16396 byte allocation with 2088 free bytes and 2088B until OOM

Probably in our library this line causes the error, but I guess nothing wrong with this that could cause OOM exception.

public TokenUtils() {
        Security.addProvider(new BouncyCastleProvider());
    }

The issue is captured on a device that has android 5.1.1, samsung, Galaxy J3(2016)

Thanks in advance.
