[
https://issues.apache.org/jira/browse/GROOVY-8891?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]
Anton Pryamostanov updated GROOVY-8891:
---
Description:
With ref. to GROOVY-8880, when instance or static field has default value in
Trait, when same Trait has Instance Init Block, Runtime exception happens.
Example code:
{code}
trait Trait {
Integer fieldWithDefaultValue = 0
{
System.out.println("Only instance init block gives this problem")
}
}
class ClassWithTrait implements Trait {
}
new ClassWithTrait().fieldWithDefaultValue
{code}
Runtime exception:
{code}
groovy.lang.MissingMethodException: No signature of method:
java.lang.Integer.call() is applicable for argument types:
(Trait$Trait$Helper$__init__closure1) values:
[Trait$Trait$Helper$__init__closure1@5833d058]
Possible solutions: wait(), abs(), any(), wait(long),
each(groovy.lang.Closure), any(groovy.lang.Closure)
at Trait$Trait$Helper.$init$(ConsoleScript80:3)
at ClassWithTrait.(ConsoleScript80)
at ConsoleScript80.run(ConsoleScript80:9)
{code}
Note: It does not matter if field is static of instance.
Note 2: Static Init Block in Trait does not cause same issue and works Ok.
However Please see issue (TBD) which can mask this problem from appearing in
Static Init Block also.
