When failing to load hsdis(Hot Spot Disassembler) library (because there is no library or hsdis.so is old and so on),
there is no warning message (only can see info level messages if put -Xlog:os=info).
This should show a warning message to tell the user that you failed to load libraries for hsdis.
So I put a warning message to notify this.

e.g.
/build/macosx-aarch64-server-fastdebug/jdk/bin/java -XX:+UnlockDiagnosticVMOptions -XX:+PrintAssembly -version

->
