------------------------------------------
Summary: Support jdk-release option for configuring the target JDK
release when doing the compilation
Key: GROOVY-11105
URL: https://issues.apache.org/jira/browse/GROOVY-11105
Project: Groovy
Issue Type: New Feature
Components: Compiler
Affects Versions: 4.0.12
Reporter: Vladimir Sitnikov
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.
{code:java}
import java.nio.ByteBuffer;
ByteBuffer bb = new ByteBuffer();
// 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();
{code}
