: That's fine - it could be a Solr bug too.
it definitely looks like a generic solr bug.
JSONResponseWriter.java:398
(in the writeSolrDocument method that supports psuedo-fields)
writeMapOpener(-1); // no trivial way to determine map size
PHPSerializedResponseWriter.java:221
(in which PHPSerializedWriter extends JSONWriter)...
public void writeMapOpener(int size) throws IOException,
IllegalArgumentException {
// negative size value indicates that something has gone wrong
if (size < 0) {
throw new IllegalArgumentException("Map size must not be
negative");
}
...it looks like PHPSerializedResponseWriter is fundementally broken.
I suspect the origin of hte problem is that PHPSerializedWriter overrides
"writeDoc" and that prevented the writeMapOpener(-1) from ever happening,
but then "writeSolrDocument" was added which PHPSerializedWriter doesn't
override that.
