Roman Stumm commented on GROOVY-8211:
-------------------------------------
I had the a similar error with Groovy 2.4.15 during groovyc of a complex class
annotated with CompileStatic:
Error:Groovyc: While compiling adm-core_main:
java.lang.ArrayIndexOutOfBoundsException: 1

> ArrayIndexOutOfBoundsException at compilation when accessing a generic type

> Key: GROOVY-8211
> URL: https://issues.apache.org/jira/browse/GROOVY-8211
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Reporter: M. Justin
> Priority: Minor
>
> When using @CompileStatic, accessing a method on a type that is specified
> using too few type parameters causes an ArrayIndexOutOfBoundsException to be
> thrown by the Groovy compiler. Furthermore, there is no indication where in
> the code the error occurs, so it can be very difficult to debug the issue.
> {code}@CompileStatic
> class GenericsCompilation {
> def method() {
> Map<String> map
> map.toString() //This line causes the issue
> }
> }{code}
> The output is:
> {code}$ groovyc GenericsCompilation.groovy
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> General error during instruction selection: 1
> java.lang.ArrayIndexOutOfBoundsException: 1
