Gary D. Gregory updated IO-717:
-------------------------------
Summary: Infinite loop in ReaderInputStream instead of throwing exception
with CodingErrorAction.REPORT (was: ReaderInputStream does not throw exception
with CodingErrorAction.REPORT)
> Infinite loop in ReaderInputStream instead of throwing exception with
> CodingErrorAction.REPORT
> ----------------------------------------------------------------------------------------------
>
> Key: IO-717
> URL: https://issues.apache.org/jira/browse/IO-717
> Project: Commons IO
> Issue Type: Bug
> Components: Streams/Writers
> Affects Versions: 2.8.0
> Reporter: Marcono1234
> Priority: Major
>
> {{org.apache.commons.io.input.ReaderInputStream}} constructed with a
> {{CharsetEncoder}} with {{CodingErrorAction.REPORT}} does not throw
> exceptions when unmappable or malformed input is encountered. And in some
> cases can even enter infinite loops.
> Example:
> {code}
> CharsetEncoder encoder =
> StandardCharsets.UTF_8.newEncoder().onMalformedInput(CodingErrorAction.REPORT);
> try (InputStream in = new ReaderInputStream(new StringReader("\uD800aa"),
> encoder, 2)) {
> in.read();
> }
> {code}
> The reason for this is that the class does not check
> [{{CoderResult.isError()}}|https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/charset/CoderResult.html#isError()]
> and then call
> [{{CoderResult.throwException()}}|https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/nio/charset/CoderResult.html#throwException()].
> ----
> It would also be good to improve the documentation of the constructors taking
> a {{Charset}} or charset name to describe that they replace unmappable or
> malformed input with the default replacement character.
