Sam Halliday created LUCENE-5923:
------------------------------------
Summary: cannot re-use Field in 4.7.2
Key: LUCENE-5923
URL: https://issues.apache.org/jira/browse/LUCENE-5923
Project: Lucene - Core
Issue Type: Bug
Reporter: Sam Halliday
I get an exception "first position increment must be > 0 (got 0) for field ..."
when I try to re-use a Field as an entry in a Document. Snippet below.
This works ok on lucene 4.9, but I have to go back to 4.7 for Java 6
compatibility.
Workaround is to not re-use the same object in each Document.
(this is Scala)
private val TypeField = new StringField("TYPE", clazz.getSimpleName,
Store.YES)
final def toDocument(t: T): Document = {
val doc = new Document
// Lucene 4.7.2 bug: re-using the common object gives
// "first position increment must be > 0 (got 0) for field 'TYPE'"
//doc.add(TypeField)
doc.add(new StringField("TYPE", clazz.getSimpleName, Store.YES))
doc.add(new StringField("ID", id(t), Store.NO))
doc
}
