IndexOutOfBoundsException thrown in AbstractSessionInputBuffer.readLine()
-------------------------------------------------------------------------
Key: HTTPCORE-263
URL: https://issues.apache.org/jira/browse/HTTPCORE-263
Project: HttpComponents HttpCore
Issue Type: Bug
Components: HttpCore
Affects Versions: 4.1.1
Environment: reported on Android 2.3.3 using repackaged httpcore
4.1.1, optimized and obfuscated with Proguard
Reporter: Michael Pujos
Priority: Minor
I've got the exception below reported in my Android app using (repackaged)
httpcore 4.1.1:
java.lang.IndexOutOfBoundsException: off: 1088 len: -1 b.length: 8192
at org.apache.http.util.CharArrayBuffer.append(SourceFile:185)

It seems to be very rare. Stack trace line number (185) in for
AbstractSessionInputBuffer doesn't match the exact line number of the offending
append() call,
but there are too such call in this function and it looks like one of them is
called with len = -1 triggering the IndexOutOfBoundsException in append()
