Pascal Schumacher updated GROOVY-7541:
--------------------------------------
Fix Version/s: (was: 2.3.7)
> GroovyBugError in TypeTransformer.addTransformer
> ------------------------------------------------
>
> Key: GROOVY-7541
> URL: https://issues.apache.org/jira/browse/GROOVY-7541
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime
> Affects Versions: 2.4.4
> Environment: Java web app on either Apache on Linux or Windows, or
> WebSphere on AIX. Java 7.1. Groovy via
> ScriptEngineManager.getEngineByName("groovy")
> Reporter: Dan Nimick
>
> Just updated from Groovy 2.3.6 to 2.4.4 and this code no longer works when
> dynamic invocation is used (works fine when indy not used):
> d1.setIndexes(new HashMap<List<String>,DatasetIndex>());
> where d1 is one of the Java classes imported to the Groovy script. setIndexes
> is just a plain setter of a field on the class. The error is
> BUG! Unknown transformation for argument <... stuff from toString of d1
> here...> at position 0 with class com.ibm.cayce.sdv.dataset.Dataset for
> parameter of type class org.codehaus.groovy.vmplugin.v7.IndyInterface
> It contains no stack trace, but by searching for sources of "Unknown
> transformation for argument", I found it to be in
> TypeTransformer.addTransformer. If I put a breakpoint there, this is the call
> stack:
> TypeTransformers.addTransformer(MethodHandle, int, Object, Class) line: 124
> Selector$MethodSelector.correctCoerce() line: 793
> Selector$MethodSelector.setCallSiteTarget() line: 958
> IndyInterface.selectMethod(MutableCallSite, Class, String, int, Boolean,
> Boolean, Boolean, Object, Object[]) line: 214
> Script2.run() line: 2
> GroovyScriptEngineImpl.eval(Class, ScriptContext) line: 323
> GroovyScriptEngineImpl.eval(String, ScriptContext) line: 124
> GroovyScriptEngineImpl(AbstractScriptEngine).eval(String) line: 276
> Looks like TypeTransformer was introduced via org.codehaus.groovy.vmplugin.v7
> in version 2.3.8, but I don't see anything in the 2.3.8 change log about it
> (at least not under an obvious description).
> FWIW, we turn on dynamic invocation via:
> CompilerConfiguration configuration = new CompilerConfiguration();
> configuration.setTargetBytecode(System.getProperty("java.specification.version"));
>
> configuration.getOptimizationOptions().put("indy", true);
> configuration.getOptimizationOptions().put("int", false);
>
> configuration.addCompilationCustomizers(importCustomizer,secureCustomizer);
> GroovyClassLoader gcl = new
> GroovyClassLoader(this.getClass().getClassLoader(), configuration);
> ((GroovyScriptEngineImpl) engine).setClassLoader(gcl);
> Please let me know if any more info is needed, or if there is a work around
> (other than not using indy).
