I took a look at LIB_FILES. Only 'ModuleInfoWriter.java' depends on advanced APIs. 
It was added to testlibrary in [JDK-8304163](https://bugs.openjdk.org/browse/JDK-8304163).

Yes, we may need to exclude more files in the future. Currently, Makefile selects LIB_FILES using wildcard matching. If it's necessary, we need to define LIB_FILES explicitly.
