So this build failure only happens because we implicitly compile the rest of the testlib, even though CTW does not use it? Because if CTW uses these, I would have expected we need the similar additions in `CtwRunner` here: https://github.com/openjdk/jdk/blob/09852884cc4f55b2c95e2dbe28cf5c7ad9095684/test/hotspot/jtreg/testlibrary/ctw/src/sun/hotspot/tools/ctw/CtwRunner.java#L274-L278
