The test class `NTLMAuthenticationGrantHandlerTest` (in *components/org.wso2.carbon.identity.oauth/src/test/java/org/wso2/carbon/identity/oauth2/token/handlers/grant/iwa/ntlm/NTLMAuthenticationGrantHandlerTest.java*) will throw an UnsatisfiedLinkError if the installed JDK in your machine targets the aarch64 (ARM) architecture. Therefore, if you want to run the test class `NTLMAuthenticationGrantHandlerTest` please make sure that a JDK that targets x64 architecture is installed in your machine.
