Hi, Someone sent me the following email, showing a problem, which triggers an interesting error message: "This method should not have been called."
Coming from here: https://github.com/apache/groovy/blob/183b8fbf0248a2dceffbba684e50c3c2c060e46c/src/main/org/codehaus/groovy/classgen/asm/sc/StaticTypesCallSiteWriter.java#L643 Guillaume ---------- Forwarded message ---------- Date: Tue, May 2, 2017 at 10:37 AM Subject: Groovy Bug? Hello, I am playing around with groovy and the map data type I then added the CompileStatic annotation and I got the following result. Since I have no deep knowledge of Groovy I can't judge what this means but since groovy mentions I should issue a bug. I have not done this via jira since I don't have an account there, but I think it is fair to inform you about this. // Ececuted with C:/Tools/Groovy/bin/groovy.bat in the following environment // Groovy Version: 2.4.10 JVM: 1.8.0_121 Vendor: Oracle Corporation OS: Windows 7 // Output // Caught: BUG! exception in phase 'class generation' in source unit 'B:\workspace\Groovy\NinjaGen\NinjaGenerator.groovy' At line 17 column 9 // On receiver: C_ASM_Files_m with message: leftShift and arguments: (java.util.Map -> java.util.Map <K extends java.lang.Object, V extends java.lang.Object>) FileListName_m.C_FILES // This method should not have been called.
