Sebb commented on IO-356:
-------------------------
Thanks for the report; added the test case:
URL: http://svn.apache.org/viewvc?rev=1406222&view=rev
Log:
IO-356 CharSequenceInputStream#reset() behaves incorrectly in case when buffer
size is not dividable by data size
Add test case showing the issue
Modified:
commons/proper/io/trunk/src/test/java/org/apache/commons/io/input/CharSequenceInputStreamTest.java
If the code "bbuf.limit(0);" is added to the reset() method the tests run OK.
However I'm not 100% sure that's the full solution; perhaps others can comment?

> Key: IO-356
> URL: https://issues.apache.org/jira/browse/IO-356
> Project: Commons IO
> Issue Type: Bug
> Components: Streams/Writers
> Affects Versions: 2.4
> Reporter: Dmitry Katsubo
> Attachments: CharSequenceInputStreamTest.java
>
>
> The size effect happens when buffer size of input stream is not dividable by
> requested data size. The bug is hidden in {{CharSequenceInputStream#reset()}}
> method which should also call (I think) {{bbuf.limit(0)}} otherwise next call
> to {{CharSequenceInputStream#read()}} will return the remaining tail which
> {{bbuf}} has accumulated.
> In the attached test case the test fails, if {{dataSize = 13}} (not dividable
> by 10) and runs OK if {{dataSize = 20}} (dividable by 10).
