Hi everyone, I was looking through the JSR-223 code in org.armedbear.lisp.scripting as I noticed that AbclScriptEngineFactory is not fully compliant to JSR-223 [1]. For the methods: - java.util.List<java.lang.String> getExtensions() - java.util.List<java.lang.String> getMimeTypes() - java.util.List<java.lang.String> getNames() _immutable_ Lists should be returned. Please find a remedying patch below.
