> the type class is set
> ------------------------------------------------------------------------------------------------
>
> Key: GROOVY-11254
> URL: https://issues.apache.org/jira/browse/GROOVY-11254
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation, Static Type Checker
> Reporter: Thodoris Sotiropoulos
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 4.0.18, 5.0.0-alpha-5

>
> I have the following well-typed program:
> {code}
> interface TemporalQuery<T1> {
> T1 queryFrom(TemporalAccessor p0);
> }
> class TemporalAccessor {}
> class Test {
> void test() {
> TemporalQuery<String> rec = null;
> TemporalQuery<String> gravy = rec::queryFrom;
> }
> }
> {code}
> The program crashes the compiler and produces the following stack trace
> {code}
> >>> a serious error occurred: BUG! exception in phase 'class generation' in
> >>> source unit 'Main.groovy' ClassNode#getTypeClass for Foo called before
> >>> the type class is set
> >>> stacktrace:
> BUG! exception in phase 'class generation' in source unit 'Main.groovy'
