Answer 1

The STS 3.8.1 all-in-one distribution is based on Eclipse v4.6 which required Java 1.8 to start it. As @Jens mentioned, you can to Open Windows -> Preferences. Then open tree node Java > Installed JREs. After adding a new JRE/JDK, you can set it as default or delete others items.

Another option: if you have installed Eclipse 4.5, please visit https://spring.io/tools/sts/all

1. Install STS 3.8.1 via Update Sites: open Help -> Install New Software.... Just paste update site URL in the Wizard.
2. If you prefer install it offline, you can download STS Update Site Archives. Clicking the Add... button in the same Wizard, select the folder of unpacked zip file.
