NOT_SUPPORTED

NOT_SUPPORTED

Error message

%s is not supported in your OS

What it means

Presto's SecureRandomGeneration.getNonBlocking requests the OS-specific non-blocking SecureRandom algorithm (e.g. NativePRNGNonBlocking or Windows-PRNG). If the JVM reports NoSuchAlgorithmException for that algorithm, it throws PrestoException NOT_SUPPORTED stating the algorithm is not supported in your OS. This indicates a JVM/OS combination lacking the expected secure-random provider.

Solutions

1. Run on a standard JVM/JRE that provides the platform non-blocking algorithm
2. Ensure the SUN security provider is enabled in java.security
3. Fall back to the default SecureRandom constructor instead of the non-blocking variant
4. Upgrade the JDK to a version supporting the algorithm for your OS

Example fix

// before
SecureRandom random = SecureRandomGeneration.getNonBlocking(); // NOT_SUPPORTED on stripped JRE
// after
SecureRandom random = new SecureRandom(); // uses default, always available

SecureRandom random;
try {
    random = SecureRandomGeneration.getNonBlocking();
} catch (PrestoException e) {
    if (NOT_SUPPORTED.equals(e.getErrorCode())) {
        random = new SecureRandom(); // portable fallback
    } else throw e;
}

When it happens

Trigger: Running on a JVM/OS without the platform's non-blocking SecureRandom algorithm registered (unusual JRE, stripped security providers, exotic OS), when code calls getNonBlocking().

Common situations: Custom/minimal JRE builds (jlink images) missing security providers; overridden java.security settings removing providers; unusual platforms where NativePRNGNonBlocking is unavailable.
