[jira] [Commented] (GROOVY-4489) Generics compilation error occurs when using less then (<) operator

Paul King commented on GROOVY-4489:
-----------------------------------

This still happens in 2.5.2 but doesn't happen in the parrot parser.

>                 URL: https://issues.apache.org/jira/browse/GROOVY-4489
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 1.7.4, 1.7.5, 2.4.3, 2.5.2
>            Reporter: asandor
>            Priority: Major
>
> The following code is throwing a compilation error (the strange code is a DSL):
> {code}
> def FloatComparison() {
>     when:
>     o.PROPerty1 < o.PROPerty2
>     
>     then:
>     result = true
> }
> Missing closing bracket '>' for generics types;
>    solution: Please specify the missing bracket! at line: 5, column: 5
> {code}
> Here are some snippets that don't produce this error:
> {code}
> def FloatComparison() {
>     when:
>     o.pROPerty1 < o.PROPerty2 //the first letter of the first variable is lowercase
>     
>     then:
>     result = true
> }
> {code}
> {code}
> def FloatComparison() {
>     when:
>     o.PROPerty1 < o.PROPerty2
>     
> //the label is removed and .x is added after result (without .x the exception occurs)
>     result.x = true
> }
> {code}
> Looking at the samples that work, this whole mess doesn't make any sense. It seems like a minor but very annoying bug in the compiler. We are working on a DSL, so we can't influence the names of the properties or anything significant that would be a proper workaround.
> (This is technically not a JUnit test case, but I think it's enough because it can be simply copied into the Groovy console and run)
