- Updated the `v1` credential provider configuration to include the `tokenAttributes.cacheType` field. This field is required and must be set to either `ServiceAccount` or `Token` when configuring a provider that uses a service account to fetch registry credentials.

                    Thread.sleep(2000); // Remaining attempts: 2 second intervals
                }
            }
        }

        // Provide more detailed error information

        if (lastException != null) {
            errorMessage += ". Last error: " + lastException.getMessage();

the stack pointer may change during any function call:
even pointers to stack data must not be kept in local variables.

<p>
Assembly functions should always be given Go prototypes,
both to provide pointer information for the arguments and results
and to let <code>go</code> <code>vet</code> check that
the offsets being used to access them are correct.
