Java Exception Handling

In case of errors, LicenseSpring SDK will throw an exception. SDK-specific exceptions always derive from the LicenseSpringException class. We have tried to wrap every exception under LicenseSpringException; please open a support ticket if you find a method where this is not the case.

LicenseSpringException - All SDK Exceptions inherit from this exception.

• LicenseSpringServerException - Any License server error is wrapped in this exception. The response is wrapped in the ErrorResponse class.

  • Server Error - If LicenseSpring API returns HTTP status in range [500, 599] then this exception will be thrown. See Errors and Response Codes for detailed messages.

  • ServerValidationException - Any License Client error is wrapped in this exception. If LicenseSpring API returns HTTP status in range [400, 499] then this exception will be thrown. See Errors and Response Codes for detailed messages.

• ClientValidationException - Thrown when some validation rule is broken. Example: if you do not provide an API key or another required field then this exception will be thrown.

  • LicenseExpiredException - Thrown if license has expired.

  • ConsumptionException - Thrown if license has expired.

  • ConfigurationException - Thrown when configuration files are misconfigured.

• InfrastructureException - The SDKs wrap IO and similar exceptions under this class.

  • ConnectionException - Thrown when the client fails to connect to the server. Examples: host unreachable, connection timeout, or connection refused. In all these scenarios the client won't receive any response from the server.

  • CloudCheckException - These exceptions are thrown only when one of the NODE_LOCKING Hardware ID Strategies is present. They all relate to failing to obtain metadata information about the instance.

    • MetadataServiceBlockedException - Thrown if connection is refused while trying to retrieve Cloud platform instance ID.

    • NotCloudPlatformException - Thrown if trying to retrieve Instance ID of a VM running on a Cloud Platform from a physical computer.

    • WrongPlatformException - Thrown if trying to retrieve Instance ID of a VM running on AWS from Azure Cloud platform or vice-versa.
