eric-milles opened a new pull request, #2397:
URL: https://github.com/apache/groovy/pull/2397
Changes to `StaticTypesTypeChooser` in Groovy 5 caused a cast exception at
runtime for statically-compiled imbalanced-`instanceof` scenarios like `if (cn
instanceof InnerClassNode || cn.isEnum())`. This traces back to the temp types
storage in STC. For the statement above, only `InnerClassNode` is saved as a
temp type. When the temp type is computed for "cn.isEnum()", `InnerClassNode`
is the result.
A small part of the GROOVY-7971 solution is to mix in the original variable
type in a scenario such as this
