javac could probably emit a better message here. In any case, can you 
add `--add-modules java.logging` to this. The issue is that you are 
compiling TestClass "as if" it's in the java.compiler module but that 
module does not require java.logging. There has been suggestions that 
--add-reads should imply --add-modules but no conclusion on that.
