Guillaume Nodet resolved SSHD-104.
----------------------------------
Resolution: Fixed
> FormatFlagsConversionMismatchException when using IBM JVM. Format String is
> invalid.
> ------------------------------------------------------------------------------------
>
> Key: SSHD-104
> URL: https://issues.apache.org/jira/browse/SSHD-104
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.5.0, 0.6.0
> Environment: IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32
> jvmxi3260sr8ifx-20100609_59383 (JIT enabled, AOT enabled)
> 2.6.35-24-generic #42-Ubuntu SMP (Ubuntu 10.10)
> Reporter: Kevin
> Priority: Critical
> Fix For: 0.6.0
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The following exception is thrown when using SFTP client FileZilla and Mina
> is running on the IBM JVM:
> java.util.FormatFlagsConversionMismatchException: Mismatched Convertor =s,
> Flags= #

> at java.lang.Thread.run(Thread.java:736)
> Latest source shows the problem line:
> 847 long length = f.getSize();
> 848 String lengthString = String.format("%1$#8s", length);
> Simple test code also reproduces the problem:
> public static void main(String [] args) {
> long length = 12312342;
> String lengthString = String.format("%1$#8s", length);
> System.out.println(lengthString);
> }
> If I understand the Formatter class documentation, I'm surprised the format
> call works at all on the Sun JVM. It says the # flag is only applicable for
> Integral types with o, x, and X conversions only. Further down in the
> documentation for 's' conversion, it says
> "If the '#' flag is given and the argument is not a Formattable , then a
> FormatFlagsConversionMismatchException will be thrown."
> Assuming the long above is autoboxed to Long, Long does not implement
> Formattable.
> I believe a different method should be used for converting this long to
> string. I'm not sure of the original intent, but maybe the the 'd'
> conversion was intended rather than the 's' conversion to output the long in
> base 10, but then I don't understand the use of #.
