[jira] Created: (DIRMINA-479) Running Wget results in
UnsupportedOperationException
Running Wget results in UnsupportedOperationException
-----------------------------------------------------
Key: DIRMINA-479
URL: https://issues.apache.org/jira/browse/DIRMINA-479
Project: MINA
Issue Type: Bug
Components: Protocol - HTTP
Affects Versions: 2.0.0-M1
Environment: with JDK 1.5 and 1.6, on Windows and Mac OS
Reporter: Sangjin Lee
Priority: Minor
Running Wget in the example results in UnsupportedOperationException, because it calls slice() on a UnderivableBuffer.
Reproducible step:
Run "org.apache.mina.example.httpclient.Wget http://www.google.com".
