Robert Muir updated LUCENE-6999:
--------------------------------
    Attachment: LUCENE-6999_test.patch

Here's a test. It just adds Points to a few of the indexing tests like disk 
full / exception handling / etc.

I see the leak with this seed:

{noformat}
ant test  -Dtestcase=TestIndexWriterOnVMError -Dtests.method=testUnknownError 
-Dtests.seed=19BD5BF64D5924E1 -Dtests.locale=vi-VN -Dtests.timezone=Asia/Baku 
-Dtests.asserts=true -Dtests.file.encoding=UTF-8
{noformat}

> Lucene60PointsWriter has a buggy close method

> This will leak a file handle on e.g. disk full or other exceptions
> {noformat}
>   @Override
>   public void close() throws IOException {
>     if (closed == false) {
>       CodecUtil.writeFooter(dataOut); // something bad happens
>       dataOut.close();
> {noformat}
> I'm not a fan of these complex close methods, should we add a finish() to the 
> codec api or similar?
