----------------------------------
Summary: 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
Fix For: 2.3.7
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).
