Wildfly log of Stdout/Stderr has one more \r at the end of each line on Windows

[anqin007]

Hi,

On Windows platform, wildfly logs stdout/stderr in files with one more \r at the end of each line. Here is the pattern format defined in standalone-full.xml:

            <formatter name="PATTERN">

                <pattern-formatter pattern="%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n"/>

            </formatter>

            <formatter name="COLOR-PATTERN">

                <pattern-formatter pattern="%K{level}%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%e%n"/>

            </formatter>

It is the default one. The output seems normal, but actually the end of line \r\r\n. It should be \r\n. Other lines logged by itself has no such issue.

It only happenson Windows. Does anyone knows the reason?

Thanks,
