Re: [jira] Commented: (HARMONY-33) java.nio.BufferOverflow exception while decoding ByteBuffer with UTF-16 charset
Andrew,
thanks for your comments. Looks like the bug in ICU is very simple and
I hope it will be fixed in the next ICU release. I just like to reopen
harmony-33 to correctly track issue status. At the moment it
reproduced with icu4jni3.4 , that's why I asked to reopen. As soon as
we get new version of ICU bug should be closed.
Thanks.
Vladimir.

Hi, Vladimir
The bug has been raised in ICU bug tracking system serveral months ago[1].
ICU has noticed this bug and will fix the bug in next release version.
Thanks.

Unfortunately the bug should be reopened. I have the next output with
Harmony33 class:
java.lang.IllegalArgumentException: The length must be positive.

at Harmony33.main(Harmony33.java:11)
It's not a regression, the problem here is inside implFlush method of
CharsetDecoderICU .
Corresponding bug was submitted to ICU already:

So, we just need to wait until we get new version of ICU library.

[jira] Commented: (HARMONY-33) java.nio.BufferOverflow exception while decoding ByteBuffer with UTF-16 charset
[
http://issues.apache.org/jira/browse/HARMONY-33?page=comments#action_12363005 ]
Vladimir Strigun commented on HARMONY-33:
-
The reason of the issue is invocation of put(replacement) method for CharBuffer
with zero capacity. First, during decoding byte buffer, char buffer should be
created with initial capacity equals to remaining bytes in byte buffer
multiplied by average chars per byte value. For the current testcase initial
capacity for char buffer is 0 ( int length = (int) (in.remaining() * averChars)
). And when CodingErrorAction = CodingErrorAction.REPLACE decoder try to put
replacement string to zero-sized char buffer.
Please review fix for the issue (diff for revision 367369 of
/incubator/harmony/enhanced/classlib/trunk/modules/nio_char/src/main/java/java/nio/charset/CharsetDecoder.java):
405a406,408
if(out.remaining() replace.length() ) {
return CoderResult.OVERFLOW;
}
