Key: HARMONY-2474
URL: http://issues.apache.org/jira/browse/HARMONY-2474
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Anton Ivanov
Priority: Minor
While trying to remove element from empty TreeSet, ClassCastException is thrown.
Test to reproduce the problem:
import java.util.TreeSet;
public class EmptyTreeRemoveTest {
public static void main(String[] args) {
TreeSet ts = new TreeSet();
Object node = new Object();
try {
ts.remove(node);
System.out.println("PASSED");
} catch (Exception e) {
System.out.println("FAILED");
e.printStackTrace();
}
}
}
Output on Harmony:
FAILED
java.lang.ClassCastException: java.lang.Object incompatible with java.lang.Comparable
at java.util.TreeMap.toComparable(TreeMap.java:79)
at java.util.TreeMap.find(TreeMap.java:98)

[jira] Resolved: (HARMONY-2474) [classlib][luni]
java.util.TreeSet.remove() throw ClassCastException while trying to remove
element from empty TreeSet
Posted by "Alexey Petrenko (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-2474?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexey Petrenko resolved HARMONY-2474.
--------------------------------------
Resolution: Fixed
NB: RI throws ClassCastExceptions when TreeSet is not empty. Harmony throws it in all cases.
So only empty TreeSet need special handling for Harmony.
The patch has been applied.
Please verify.
