RangeQuery equals method does not compare collator property fully
-----------------------------------------------------------------
Key: LUCENE-1587
URL: https://issues.apache.org/jira/browse/LUCENE-1587
Project: Lucene - Java
Issue Type: Bug
Components: Search
Affects Versions: 2.4.1
Reporter: Mark Platvoet
Priority: Minor
The equals method in the range query has the collator comparison implemented as:
(this.collator != null && ! this.collator.equals(other.collator))
When _this.collator = null_ and _other.collator = someCollator_ this method
will incorrectly assume they are equal.
So adding something like
|| (this.collator == null && other.collator != null)
would fix the problem
