[jira] [Created] (GROOVY-9652) ClassCastException for comparison to
single-character string literal in closure
Eric Milles created GROOVY-9652:
-----------------------------------
Summary: ClassCastException for comparison to single-character string literal in closure
Key: GROOVY-9652
URL: https://issues.apache.org/jira/browse/GROOVY-9652
Project: Groovy
Issue Type: Bug
Affects Versions: 2.5.13
Reporter: Eric Milles
This started failing with Groovy 2.5.13:
{code:groovy}
class Node {
String name, text
}
class Root implements Iterable<Node> {
@Override
Iterator<Node> iterator() {
return [
new Node(name: 'term', text: 'foo'),
new Node(name: 'dash', text: '-' ),
new Node(name: 'term', text: 'bar')
].iterator()
}
}
@groovy.transform.CompileStatic
void test() {
Root root = new Root()
root[0].with {
assert name == 'term'
assert text == 'foo'
}
root[1].with {
assert name == 'dash'
assert text == '-' // GroovyCastException: Cannot cast object 'script@b91d8c4' with class 'script' to class 'bugs.Node'
}
}
test()
{code}
I noticed some changes in {{BinaryExpressionTransformer#tryOptimizeCharComparison}} that may be relevant.
