Mirza Hadzic commented on LUCENE-1091:
--------------------------------------
I found the reason: Only when running in *debug* mode (NetBeans) JVM takes vast
amount of virtual memory . In "normal mode" everything works as expected. Seems
something is wrong with debug mode of JVM, but thats nothing to do with
Lucene.I will report to NetBeans.

> This little program eats incrementally 2MB of virtual RAM per each 1000
> documents indexed, only when Field.Index.TOKENIZED used :
> public Document getDoc() {
> Document document = new Document();
> document.add(new Field("foo", "foo bar", Field.Store.NO,
> Field.Index.TOKENIZED));
> return document;
> }
> public Document run() {
> IndexWriter writer = new IndexWriter(new File(jIndexFileName), new
> StandardAnalyzer(), true);
> for (int i = 0; i < 1000000; i++) {
> writer.addDocument(getDoc());
> }
> }
