If you try to run a build with a build id that contains commas (e.g. via jprt using -id 12345,12345), the build will fail with the following error:

make[3]: Leaving directory '.../make'
make/Main.gmk:183: recipe for target 'java.base-launchers' failed
Launcher-java.base.gmk:40: *** missing separator. Stop.
make[2]: *** [java.base-launchers] Error 1
make[2]: *** Waiting for unfinished jobs....

This worked before.
