I just switched to the Java 9.0.1 runtime, and Nashorn now fails to parse the Coffeescript compiler, which worked fine in Java 8_144.
Coffeescript 2 compiler: http://coffeescript.org/v2/browser-compiler/coffeescript.js v1 also fails: http://coffeescript.org/v1/browser-compiler/coffee-script.js Exception is: javax.script.ScriptException: SyntaxError: unexpected in <eval> at line number 39 at column number 249736 at jdk.scripting.nashorn/jdk.nashorn.api.scripting.NashornScriptEngine.throwAsScriptException(NashornScriptEngine.java:469) at jdk.scripting.nashorn/jdk.nashorn.api.scripting.NashornScriptEngine.evalImpl(NashornScriptEngine.java:425) at jdk.scripting.nashorn/jdk.nashorn.api.scripting.NashornScriptEngine.access$300(NashornScriptEngine.java:72) at jdk.scripting.nashorn/jdk.nashorn.api.scripting.NashornScriptEngine$3.eval(NashornScriptEngine.java:513) at java.scripting/javax.script.CompiledScript.eval(CompiledScript.java:92) at scuff.js.CoffeeScriptCompiler.compile(CoffeeScriptCompiler.scala:115) at scuff.js.TestCoffeeScriptCompiler.cs2(TestCoffeeScriptCompiler.scala:114) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:564) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:539) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:761) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:461) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:207) Caused by: <eval>:39:249736 SyntaxError: unexpected at jdk.scripting.nashorn/jdk.nashorn.internal.objects.NativeError.initException(NativeError.java:135) at jdk.scripting.nashorn/jdk.nashorn.internal.objects.NativeSyntaxError.<init>(NativeSyntaxError.java:73) at jdk.scripting.nashorn/jdk.nashorn.internal.objects.NativeSyntaxError.<init>(NativeSyntaxError.java:77) at jdk.scripting.nashorn/jdk.nashorn.internal.objects.NativeSyntaxError.constructor(NativeSyntaxError.java:98) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$2368$6956AA$\^eval\_.L:39-1#a#L:39-1#L:39#throwSyntaxError(<eval>:39) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$2364$253073AA$\^eval\_$cu1$restOf.L:39-1#a#L:39-8#L:39#parseError(<eval>:39) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$2359$\^eval\_$cu1$restOf.L:39-1#a#L:39-4#o#parse(<eval>:39) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$2343$\^eval\_$cu1$restOf.L:39-1#a#L:39-8#L:39#p(<eval>:39) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$2056$250675AA$\^eval\_.L:39-1#a#L:39-8#L:39#T#L:39(<eval>:39) at jdk.scripting.nashorn.scripts/jdk.nashorn.internal.scripts.Script$Recompilation$1572$\^eval\_.:program(<eval>:41) at jdk.scripting.nashorn/jdk.nashorn.internal.runtime.ScriptFunctionData.invoke(ScriptFunctionData.java:652) at jdk.scripting.nashorn/jdk.nashorn.internal.runtime.ScriptFunction.invoke(ScriptFunction.java:513) at jdk.scripting.nashorn/jdk.nashorn.internal.runtime.ScriptRuntime.apply(ScriptRuntime.java:517) at jdk.scripting.nashorn/jdk.nashorn.api.scripting.NashornScriptEngine.evalImpl(NashornScriptEngine.java:420) ... 28 more
