Our company has upgraded to Groovy 4 and JDK 21. However, one platform we support, MVS, only supports a JDK 8 runtime.

When running a class compiled with Groovy 4, an exception results:

... java.lang.UnsupportedClassVersionError: JVMCFRE199E bad major version 61.0 of class=..., the maximum supported major version is 52.0; offset=6

Can we cross-compile or force Groovy to generate bytecodes that support JDK 8?

I appreciate any help you can provide.
