Description
See the motivation and description in Kotlin: https://youtrack.jetbrains.com/issue/KT-29974/Add-a-compiler-option-Xjdk-release-similar-to-javacs-release-to-control-the-target-JDK-version
Sample code that requires jdk-release option for a proper compilation, and it could not be solved with "target bytecode version" alone.
@groovy.transform.CompileStatic test() { def bb = java.nio.ByteBuffer.wrap(new byte[8]) // it should compile to invokevirtual Buffer.flip()Ljava.nio.Buffer; // when compiling for Java 1.8 since Java 1.8 does not have ByteBuffer flip() override in ByteBuffer // However, if the build uses JDK17 for execution, then it contains ByteBuffer flip() override, // and Groovy would compile it to invokevirtual ByteBuffer.flip()Ljava.nio.ByteBuffer // which would fail to execute in Java 1.8 bb.flip() } test()
