However, the latest Java version may only be supported for compilation or testing, not for running Gradle.
Support is achieved using <<toolchains#toolchains,toolchains>> and applies to all tasks supporting toolchains.

See the table below for the Java version supported by a specific Gradle release:

.Java Compatibility
|===
|Java version | Support for toolchains | Support for running Gradle

 * There are many different ways to run a process in Groovy, and all are producing different byte code.
 * The class supports compiling Groovy code in both indy and old-school CallSite modes.
