Uwe Schindler updated SOLR-4275:
--------------------------------
Attachment: SOLR-4275.patch
Simle patch. It also corrects the read logic so it also works with unbuffered
input readers.
> TrieTokenizer causes StringIOOBE when input is empty instead of returning no
> token

> Key: SOLR-4275
> URL: https://issues.apache.org/jira/browse/SOLR-4275
> Project: Solr
> Issue Type: Bug
> Affects Versions: 4.0
> Reporter: Uwe Schindler
> Assignee: Uwe Schindler
> Fix For: 4.1, 5.0

> Attachments: SOLR-4275.patch

>
> When you use the admin interface and select a trie field (e.g. tint) and
> enter nothing into the field, the tokenizer should normally return no tokens.
> TrieTokenizer instead gets and SIOOBE because read() into the charbuffer
> returns -1 (end of stream). This is used to initialize the string's length...
> The fix is to modify the tokenizer to behave like a real tokenizer:
> - after reading the input, check if empty (read < 0) and then use 0 as length
> - if the resulting string is empty (total len == 0), set a boolean to false
> and make the incrementToken/end methods not delegate and return false.
