Java SDK

the docid\ uwqr7jqg01pcftet8iao0 module embodies essential license functionalities, encompassing tasks like online and offline license activation and deactivation, provisioning trial licenses, recording usage instances, and monitoring variables the docid 85ozdmi ceei i5t6ldh7 serves as the foundational module with a specific emphasis on floating license functionalities for a deeper understanding of floating licenses, additional information can be accessed by referring to the provided resource on docid 4aunypial8i2te4nyppx7 the docid\ oqehm3fli2mj 0aq8u724 module offers a collection of apis designed to generate license keys and facilitate order placement for further details about the general management api, see our docid\ abk8afs7gbmtujl rd 4p minimum java version for this sdk is 8 161 if you are unsure which sdk module to implement, visit docid 6ydrwccxdnln9fw4zya4 to learn what each module offers from version 2 2 0 onwards, you can find all the release artifacts direct downloads, including hosted javadoc links on our docid\ dm ksn9s vvhglpywsm5x page release notes february 10th, 2026, v2 27 0 license client new added fields to licensedata islicensed, isvalid, isexpired, licenseactive, licenseenabled, floatinginusedevices, maxlicenseusers, signature, startdate, trialdays, policyid, and others floating client new added support for floating server v2 2 0 (except license bundles) updated docid 3eg92a6tmn hi0ddt9we3 with full api reference including getlicenseusers(), getlicensefeatures(), offline/airgap methods, configuration endpoints, and typical integration flow february 3rd, 2026, v2 26 2 license client add schema v2 support for offline deactivation request (activation request already has it) december 9th, 2025, v2 26 1 license client fix character encoding issue in offline license signature verification fixed string getbytes() call in authorizationservice checksignature() to explicitly use utf 8 encoding previously, signature verification would fail when jvm default charset was not utf 8 (e g , windows 1250 ) and license contained non ascii characters (e g , customer names like "józsef", "pelikán") new added nodelete variants for offline deactivation methods offlinedeactivationfilenodelete(license license, string destination) generates deactivation file without clearing local license storage offlinedeactivationstreamnodelete(license license, outputstream outputstream) writes deactivation request to stream without clearing local license storage use these methods when you need to ensure the deactivation data is safely persisted before clearing the license, then call clearlocalstorage() manually floating client fix connection leak in proxyfloatingservice fixed response body not being closed in serverhealthy() , setpassword() , setkeys() , and unregisterall() methods this was causing okhttp warnings "a connection was leaked did you forget to close a response body?" december 2nd, 2025, v2 26 0 license client added encryptionkey configuration parameter to licensespringconfiguration allows setting a custom, stable encryption key for local license file ( license key ) encryption decouples license file encryption from authentication credentials (sharedkey/clientsecret) useful when using oauth authentication where the clientsecret may rotate added automatic migration support in encryptedfilelicenserepository on load, if decryption with the primary key fails, the sdk will attempt to decrypt using fallback keys (sharedkey, clientsecret) if successful, the license is automatically re saved with the new encryption key migration guide to migrate from clientsecret based encryption to a stable encryptionkey configure both the current clientsecret and the new encryptionkey licensespringconfiguration config = licensespringconfiguration builder() clientid("your client id") clientsecret("current client secret") productcode("product") encryptionkey("your stable encryption key") build(); on first load(), the sdk will try to decrypt with encryptionkey (fails for existing files) fall back to clientsecret (succeeds) automatically re save the license encrypted with encryptionkey future oauth secret rotations will not affect the license file encryption november 19th, 2025, v2 25 2 all added floatinginusedevices and floatinginuse to licensefeature (used with floating server) floating client changed signature verification to use decoder instead of interceptor for floating v2 api (was consuming body stream too early, causing problems with other

generated code higher coverage with javadoc on all java sdks license client sdk added a grace period configuration option, which resolves the remote check services to a local license check with a grace period from 1 to 5 days note that the grace period applies only to the check method and for infrastructural problems (connection, server error) license validation exceptions are still thrown default behaviour is off added throws licensespringexception to every licensemanager method (unchecked) enabled negative increments of consumptions defaults to disabled in configuration removed the option to place orders from the client sdks floating client sdk implemented an automated shutdown hook background thread the thread releases activated licenses and deactivates the license by default the shutdown hook is enabled, and can be disabled added a per process (uuid) generated hardware id strategy which works well with the floating license model defined a checksubscriber interface which can be used to subscribe to background check events default implementation ignores the incoming events added a background periodic check caller for all activated licenses deactivation removes the
