Groovy 3.0.13

What's new in this version:

Fixed:
- @CompileStatic fails to unify types
- STC: type argument not applied to error message
- Wrong type argument inference when using the result of ternary operator directly.
- STC: error when passing a type parameter in type constructor
- STC: Guava Multimap#asMap bridge method
- STC: instanceof and DGM each(Map,Closure)
- Type inference does not work with GDK class enhancements
- Question mark in the attribute for a class name
- STC: cannot return closure from method without casting
- STC: no error for incompatible type bounds on return value
- STC fails to substitute type variable when using the diamond operator and calling a closure
- Variable's inferred type is upcasted to an Object
- Unable to infer type variable of parameterized function that expects two parameters
- Type variable substitution does not work properly on parameterized function's return type
- Type variable of function does not shadow the corresponding type variable of class
- STC rejects program on compiling constructor initialization with a wildcard type
- Wrong type argument is inferred on combining use-site variance and diamond operator
- Unable to resolve method after LUB operator
- STC fails to infer the correct type for type variable in the presence of the diamond operator and bounded polymorphism
- Random order of TraitBridge methods breaks cachability
- ToString order bug for super properties
- CompileStatic doesn't call asBoolean
- Resolving wrong overloaded method?
- Regression in STC related to generics, unknown cause
- Exceptions thrown from MarkupTemplateEngine when map accessors and GString interpolation are used
- STC doesn't resolve zero-argument method references in nested generics
- Groovydoc deprecation list page is always empty even if @deprecated is used in groovydoc comments on some elements
- STC method pointer or reference to generated property method
- STC permits incorrect void method reference
- STC support assignment of primitives to interface types like Comparable and Serializable
- STC: closure/lambda/reference parameter as type witness for SAM type generics
- STC: parameterized and bounded return value for java class property
- spreadMap type inference is incorrect and STC reports on valid code
- Lack of compilation error while statically compiled the closure.
- Compile error when using generic type with lower bound
- Make for-in null safe for CompileStatic
- STC Method resolution fails if other methods with more parameters exist
- Union types incorrectly resolved
- instanceof with || inserts wrong cast
- NPE when processing the AST of nested annotations from JAR files

Dependency upgrade:
- Bump Spock to 2.2 (test dependency)

Improvement:
- SC: further optimize cast to bool
- Improve error message for malformed grab coordinate
- The use method for Category classes can't take an interface with static methods due to a NPE
