James Kleeh updated GROOVY-8260:
--------------------------------
Description:
There are many times I find myself having to cast variables directly inside an
{{instanceof Class}} check.
In addition, I have found a specific problem with a generic {{<T extends
SomeClass>}} where a method in the class that returns {{T}}, Groovy believes a
collection is being returned.
The goal of this issue is to have the following codebase compile without
changes.
{{git clone -b broken_compilation https://github.com/grails/gorm-graphql}}
Attempt to compile with {{./gradlew clean classes}}
