[jira] [Commented] (DIRAPI-320) ClassCastException on Objects.equals(Value,Value) for userPassword attribute

["Emmanuel Lecharny (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DIRAPI-320?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16611750#comment-16611750 ] 

Emmanuel Lecharny commented on DIRAPI-320:
------------------------------------------

Hi,

it's a bit hard to know what can be wrong, as you just provide a few snippet of code and a limited stack trace

Can you provide the code you used before calling {{Objects.equals(val, attribute.get())}} ?

Also provide the full stackTrace.

Thanks !

>                 URL: https://issues.apache.org/jira/browse/DIRAPI-320
>             Project: Directory Client API
>          Issue Type: Bug
>    Affects Versions: 2.0.0.AM2
>            Reporter: Pavel Zlámal
>            Priority: Minor
>
> When I use _JarLdifSchemaLoader_ it seems to load _userPassword_ attribute type with different Comparator than when I load it from LDAP connection (openLDAP in my case).
> Then If I call:
> {code:java}
> Objects.equals(val, attribute.get())
> {code}
> to check if value passed to my method is the first in the attribute, I get _ClassCastException_, since it tries to pass _String_ (normalized value) to the _ByteArrayComparator._
> When I use Schema only loaded from connection, then it works, since it uses _ComparableComparator._
> {code:java}
> java.lang.ClassCastException: java.lang.String cannot be cast to [B
>     at org.apache.directory.api.ldap.model.schema.comparators.ByteArrayComparator.compare(ByteArrayComparator.java:32)
>     at org.apache.directory.api.ldap.model.entry.Value.equals(Value.java:1389)
>     at java.util.Objects.equals(Objects.java:59)
> {code}
> So there is probably bug in schema ldif included in JAR or in equals() implementation of Value.
