Isaac Dooley updated GROOVY-8327:
---------------------------------
Description:
The parser in 2.5, 2.6, 3.0 gives a MultipleCompilationErrorsException on code
that compiled successfully in 2.4
{code:java|title=Code that fails to compile on 2.6.0-alpha-1}
class A {
static String g() { }
A() {
this({g()}) // It is ok to create a closure that calls g() in a
constructor, but not if it is being passed into this().
}
A(a) { }
}
{code}
{code:java|title=compilation error message}
$ groovyc test.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 4: Can't access instance method 'g' before the class is constructed
@ line 4, column 15.
this({g()}) // It is ok to create a closure that calls g() in a
constructor, but not if it is being passed into this().
^
1 error
{code}
My opinion is that groovy should allow users to call a static method inside a
constructor before the instance has been fully constructed, but I'm not aware
of the details of why this is disallowed in 2.6.0-alpha-1.
