--------------------------------------
Summary: JXPath size() of a uninitialized array return 1 instead
of 0
Key: JXPATH-205
URL: https://issues.apache.org/jira/browse/JXPATH-205
Project: Commons JXPath
Issue Type: Bug
Affects Versions: 1.4.0
Reporter: Samuel Zihlmann
Since version 1.4.0 JXPath size() of a uninitialized array return 1 instead of 0
In version 1.3 following unittest did work:
{code:java}
@Test
public void testSize() {
Foo foo = new Foo();
foo.setTitle("title");
Bar bar = new Bar();
//bar.setWords(List.of("Bla", "Bli", "Blub"));
//bar.setWords(List.of("Bla"));
foo.setBar(bar);
JXPathContext fallCtx = JXPathContext.newContext(foo);
String query = "size(bar/words)";
Object result = fallCtx.getValue(query);
Assert.assertEquals(0, result);
}
public static class Foo {
private Bar bar;
private String title;
public Bar getBar() {
return bar;
}
public void setBar(Bar bar) {
this.bar = bar;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
public static class Bar {
private List<String> words;
public List<String> getWords() {
return words;
}
public void setWords(List<String> words) {
this.words = words;
}
}{code}
Result Version 1.4.0:
{code:bash}
java.lang.AssertionError:
Expected :0
Actual :1
