Wrong isHex()-method in HTMLStripCharFilter
-------------------------------------------
Key: SOLR-2819
URL: https://issues.apache.org/jira/browse/SOLR-2819
Project: Solr
Issue Type: Bug
Affects Versions: 3.4
Reporter: Bernhard Berger
Priority: Trivial
In org.apache.solr.analysis HTMLStripCharFilter use a wrong isHex()-method that
return characters like 'X', 'Y' as valid hex chars:
{code}
private boolean isHex(int ch) {
return (ch>='0' && ch<='9') ||
(ch>='A' && ch<='Z') ||
(ch>='a' && ch<='z');
}
{code}
If only characters from [0-9a-zA-Z] are allowed, the readNumericEntity method
will detect faster a mismatch.
