------------------------------------
Summary: CharsetMatch.getString can get stuck in infinite loop
Key: TIKA-3080
URL: https://issues.apache.org/jira/browse/TIKA-3080
Project: Tika
Issue Type: Bug
Components: parser
Affects Versions: 1.24
Reporter: Vikram Shrowty
In here:
[https://github.com/apache/tika/blob/fb5a191edac2cef28c0a4ac390c9156acdc9e673/tika-parsers/src/main/java/org/apache/tika/parser/txt/CharsetMatch.java#L147-L150]
If you specify a maxLength and the stream is long enough, the max variable in
the loop goes to zero and the loop then gets stuck because you're asking to
read 0 bytes but not exiting unless the number of bytes read is < 0.
Looks like the condition ought to be > 0 instead of >= 0.
