Groovy static methods with dots - groovy

Question

Why do I have a compilation error for this code:
class SomeList {
final String field
SomeList(String field) {
this.field = field
}
static SomeList "Regular name of method"() {
return new SomeList("Regular name of method")
}
static SomeList "Name with.dot"() {
return new SomeList("Name with.dot")
}
}
class SomeListTests {
#Test
def "some list test"() {
//given
SomeList list = SomeList()
//when
list."Regular name of method"()
//then
//compilation error
}
}
Error message:
Error:Groovyc: While compiling tests of example-project_test: BUG! exception in phase 'semantic analysis' in source unit '/home/alex/Projects/example-project/src/test/groovy/SomeListTests.groovy' Problem loading class SomeList
I did not find any restrictions in the documentation for method names as String.
When i create main method with GroovyShell and try to start script with this method it compiles.
class Main {
public static void main(String[] args) {
GroovyShell shell = new GroovyShell()
shell.run(new File("path/to/Script.groovy"), Collections.emptyList())
println "Everything is cool"
}
}
And this is Script.groovy:
SomeList."Regular name of method"()
SomeList."Name with.dot"()

I create Test.groovy file as Groovy Script file in IDEA:
import org.junit.Test
class SomeList {
final String field
SomeList(String field) {
this.field = field
}
static SomeList "Regular name of method"() {
return new SomeList("Regular name of method")
}
static SomeList "Name with.dot"() {
return new SomeList("Name with.dot")
}
}
class SomeListTests {
#Test
void "some list test"() {
//given
SomeList list = new SomeList()
//when
println list."Regular name of method"()
//then
println list."Name with.dot"()
}
}
And it works fine for me. I'm using Groovy 2.4.15.
The output is:
SomeList#cb51256
SomeList#59906517
