[jira] Created: (SOLR-1382) TokenizerChain ClassCastException
TokenizerChain ClassCastException
---------------------------------
Key: SOLR-1382
URL: https://issues.apache.org/jira/browse/SOLR-1382
Project: Solr
Issue Type: Bug
Components: Analysis
Affects Versions: 1.4
Reporter: Simon Glentworth
Fix For: 1.4
TokenizerChain casts the result of create method in TokenizerFactory to Tokenizer.
{noformat}
public TokenStreamInfo getStream(String fieldName, Reader reader) {
Tokenizer tk = (Tokenizer)tokenizer.create(charStream(reader));
{noformat}
The TokenizerFactory interface specifies a return type of TokenStream not Tokenizer.
{noformat}
/** Creates a TokenStream of the specified input */
public TokenStream create(Reader input);
{noformat}
Tokenizer is a subclass of TokenStream and TokenizerChain is luckily working in most cases since most token factories return a Tokenizer. The following token factories return a TokenStream and will cause a ClassCastException.
HTMLStripWhitespaceTokenizerFactory
HTMLStripStandardTokenizerFactory
PatternTokenizerFactory
TrieTokenizerFactory

I think these should all be fixed in trunk? See SOLR-1377
