Java 8 ha raggiunto la fine del supporto
e verrà
ritirato
il 31 gennaio 2026. Dopo il ritiro, non potrai eseguire il deployment di applicazioni Java 8, anche se la tua organizzazione ha utilizzato in precedenza un criterio dell'organizzazione per riattivare i deployment di runtime legacy. Le tue applicazioni Java 8 esistenti continueranno a essere eseguite e a ricevere traffico dopo la
data di ritiro. Ti consigliamo di
eseguire la migrazione all'ultima versione supportata di Java.

Librerie client di Cloud per Java
Intestazioni di richiesta e risposte
Le API in questa sezione sono ancora supportate, ma non sono più consigliate.
Utilizza invece le librerie client di Cloud.
Le app che utilizzano queste API sostituite dovranno eseguire la migrazione alle librerie client Cloud e ad altri servizi prima di eseguire l'upgrade a runtime Google Cloud più recenti o ad altri ambienti che supportano Java.
