Description
I have a Server/Client software that I have created which has a server process that accepts connections from clients that transmit data about local connection information. This data is than buffered and a ThreadPoolExecutor runs to take the data and put it into a lucene index as well as a facet index. This works perfect for the lucene index, but the facet index randomly generates a NegativeArraySizeException. I cannot find any reason why the exception would be caused because lines with the same type of data do not throw it, then all of a sudden the exception is thrown, typically 4 of them in a row. I talked with mikemccand on IRC and he requested I submit this issue.
After some discussion, he seems to think it's because some of the values I am using are rather large.
Here is the exception...

Here is an example data entry which appears when the exception occurs...
Location: nj
LocalIP: 10.1.200.187
RemoteIP: 41.161.197.166
LocalPorts: [443]
Connections: 1
Times: [120]
Timestamp: 2013-06-09T12:51:00.000-07:00
States: ["Established"]
And here is the the code stripped down to provide an example of how I am handling the facet/doc code.
doc.add(new TextField("Location", ehost[0], Field.Store.YES));
cats.add(new CategoryPath("Location", doc.get("Location")));
doc.add(new TextField("LocalIP", (String) stat.get("LocalIP"), Field.Store.YES));
cats.add(new CategoryPath("LocalIP", doc.get("LocalIP")));
doc.add(new TextField("RemoteIP", (String) stat.get("RemoteIP"), Field.Store.YES));
cats.add(new CategoryPath("RemoteIP", doc.get("RemoteIP")));
doc.add(new TextField("LocalPorts", StringUtils.join(stat.get("LocalPorts"), ","), Field.Store.YES));
cats.add(new CategoryPath("LocalPorts", doc.get("LocalPorts")));
doc.add(new TextField("RemotePorts", StringUtils.join(stat.get("RemotePorts"), ","), Field.Store.YES));
cats.add(new CategoryPath("RemotePorts", doc.get("RemotePorts")));
doc.add(new LongField("Connections", (Long) stat.get("Connections"), Field.Store.YES));
cats.add(new CategoryPath("Connections", doc.get("Connections")));
doc.add(new TextField("Times", StringUtils.join(stat.get("Times"), ","), Field.Store.YES));
cats.add(new CategoryPath("Times", doc.get("Times")));
doc.add(new TextField("Timestamp", (String) stat.get("Timestamp"), Field.Store.YES));
cats.add(new CategoryPath("Timestamp", doc.get("Timestamp")));
doc.add(new TextField("States", StringUtils.join(stat.get("States"), ","), Field.Store.YES));
cats.add(new CategoryPath("States", doc.get("States")));
System.out.println("Location: "doc.get("Location")" LocalIP: "doc.get("LocalIP")" RemoteIP: "doc.get("RemoteIP")" LocalPorts: "doc.get("LocalPorts")" Connections: "doc.get("Connections")" Times: "doc.get("Times")" Timestamp: "doc.get("Timestamp")" States: "+doc.get("States"));
if (cats.size()!=0) {
FacetFields ff = new FacetFields(Main.twriter);
ff.addFields(doc, cats); // <-- Exception occurs here randomly
}
