>             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)
> 	at org.apache.http.impl.io.AbstractSessionInputBuffer.readLine(SourceFile:251)

> It seems to be very rare. Stack trace line number (185) in AbstractSessionInputBuffer
doesn't exaclty match the exact line number of the offending append() call (probably due to
Proguard).
> However,  there are 2 append() calls in readLine(), and it looks like one of them is
called with len = -1, triggering the IndexOutOfBoundsException in append()
