---------------------------------
Summary: Static compilation requires casting inside instanceof
check (additional cases)
Key: GROOVY-8336
URL: https://issues.apache.org/jira/browse/GROOVY-8336
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 2.4.12
Environment: macOS JDK 1.8
Reporter: James Kleeh
Assignee: Paul King
Fix For: 2.4.13
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. This is the line in question:

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}}
