Summary: StringIndexOutOfBoundsException in parser/EscapeQuerySyntaxImpl.java Key: LUCENE-8572 URL: https://issues.apache.org/jira/browse/LUCENE-8572 Project: Lucene - Core Issue Type: Bug Components: core/queryparser Affects Versions: 6.3 Reporter: Octavian Mocanu With "lucene-queryparser-6.3.0", specifically in "org/apache/lucene/queryparser/flexible/standard/parser/EscapeQuerySyntaxImpl.java" when escaping strings containing extended unicode chars, and with a locale distinct from that of the character set the string uses, the process fails, with a "java.lang.StringIndexOutOfBoundsException". The reason is that the comparison is done by previously converting all of the characters of the string to lower case chars, and by doing this, the original string size isn't anymore the same, but less, as of the transformed one, so that executing org/apache/lucene/queryparser/flexible/standard/parser/EscapeQuerySyntaxImpl.java:89 fails with a java.lang.StringIndexOutOfBoundsException. I wonder whether the transformation to lower case is really needed when treating the escape chars, since by avoiding it, the error may be avoided. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
