Description
The string concatenation for Map instance of Groovy is not aligned with Java, e.g. the following code can not work:
[a:1] + ' is a map'
Here are the error messages:
groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.plus() is applicable for argument types: (String) values: [ is a map] Possible solutions: plus(java.util.Collection), plus(java.util.Map), values(), values(), values(), put(java.lang.Object, java.lang.Object) at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:72) at org.codehaus.groovy.vmplugin.v8.IndyGuardsFiltersAndSignatures.unwrap(IndyGuardsFiltersAndSignatures.java:172) at org.codehaus.groovy.vmplugin.v8.IndyInterface.fromCache(IndyInterface.java:318) at ConsoleScript2.run(ConsoleScript2:1) at groovy.lang.GroovyShell.runScriptOrMainOrTestOrRunnable(GroovyShell.java:268) at groovy.lang.GroovyShell.run(GroovyShell.java:374) at groovy.lang.GroovyShell.run(GroovyShell.java:353) at groovy.lang.GroovyShell.run(GroovyShell.java:179) at groovy.console.ui.Console$GroovySourceType.run(Console.groovy:1189) at groovy.console.ui.Console.doRun(Console.groovy:1421) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104) at java.base/java.lang.reflect.Method.invoke(Method.java:577) at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:343) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:328) at org.codehaus.groovy.runtime.metaclass.ClosureMetaClass.invokeMethod(ClosureMetaClass.java:342) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.callCurrent(PogoMetaClassSite.java:63) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callCurrent(AbstractCallSite.java:203) at groovy.console.ui.Console$_runScriptImpl_closure23.doCall(Console.groovy:1385) at groovy.console.ui.Console$_runScriptImpl_closure23.doCall(Console.groovy) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104) at java.base/java.lang.reflect.Method.invoke(Method.java:577) at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:343) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:328) at org.codehaus.groovy.runtime.metaclass.ClosureMetaClass.invokeMethod(ClosureMetaClass.java:279) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1009) at groovy.lang.Closure.call(Closure.java:418) at groovy.lang.Closure.call(Closure.java:412) at groovy.lang.Closure.run(Closure.java:500) at java.base/java.lang.Thread.run(Thread.java:833)
