Crashed on normal jdk when native libraries can't load

[mio-19]

My application crashed on a special environment where all so native libraries can't work. Are they required or can graaljs run in interpreter mode without them?

Yes, GraalJS can run in interpreter-only mode using the fallback runtime, by removing the truffle-runtime jars from the module (or class) path.
For that, it's probably enough to just replace the org.graalvm.polyglot:js maven dependency with org.graalvm.js:js-language.

Is it possible to auto fallback? I don't want to prepare a special jar or class path for this environment.

You can also run with the system property truffle.UseFallbackRuntime set to true, i.e.:
-Dtruffle.UseFallbackRuntime=true.
(You'll probably want to combine it with -Dpolyglot.engine.WarnInterpreterOnly=false.)
