Justin Guertin created GROOVY-7602:
--------------------------------------
Summary: Intersect returns an empty list when the contents of the
compared Collections are Maps
Key: GROOVY-7602
URL: https://issues.apache.org/jira/browse/GROOVY-7602
Project: Groovy
Issue Type: Bug
Affects Versions: 2.3.11
Environment: Mac OS X 10.9.5
Oracle Java 1.8.0_60
Reporter: Justin Guertin
When I compare two lists with intersect and both lists contain maps I do not
get any results, even if the contents are equivalent. The test fails in Groovy
2.3.11, but passes in 2.3.7.
{code}
import org.junit.Test
class IntersectTest {
@Test
void testIntersect() {
def list1 = [[language: 'Java'], [language: 'Groovy'], [language:
'Scala']]
def list2 = [[language: 'Groovy'], [language: 'JRuby'], [language:
'Java']]
def intersection = list1.intersect(list2)
assert list1[0] == list2[2] // proves that there should be intersecting
values
println "Intersection: $intersection"
assert intersection == [[language: 'Groovy'], [language: 'Java']]
}
}
{code}
The intersect call returns an empty list in 2.3.11, resulting in the following
output:
{code}
Intersection: []
Assertion failed:
assert intersection == [[language: 'Groovy'], [language: 'Java']]
| |
[] false
