Henri Yandell updated SANDBOX-44: --------------------------------- Component: Compress > [compress] TarInputStream.read() returns wrong values > ----------------------------------------------------- > > Key: SANDBOX-44 > URL: http://issues.apache.org/jira/browse/SANDBOX-44 > Project: Commons Sandbox > Type: Bug > Components: Compress > Versions: Nightly Builds > Environment: Operating System: All > Platform: All > Reporter: Christian Kohlschütter > > There is a bug in the read() method of sandbox' compress TarInputStream, which > will be triggered only when bytes greater than 127 are being read because of a > bad implicit cast from "byte" to "int" (values >= 128 result in negative int > values, because "byte" is signed). I discovered this when applying a > DataInputStream, which makes heavy use of InputStream.read(). > Possible Fix: > Change the "return" line from the TarInputStream.read() function from > return (int)m_oneBuf[ 0 ]; > to > return (int) (m_oneBuf[0] & 0xFF); > Best regards, > Christian -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
