[jboss-jira] [JBoss JIRA] (WFLY-796) Servlet response contains DOS-style EOL characters

Servlet response contains DOS-style EOL characters -------------------------------------------------- Key: WFLY-796 URL: https://issues.jboss.org/browse/WFLY-796 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (JBoss Web) Environment: Mac OS Reporter: Cheng Fang Assignee: Remy Maucherat Attachments: test.war I'm running AS7 on Mac, but found sometimes my servlet PrintWriter produces output with dos-style eol. When opening the output in vi, there are a couple of ^M at end of line. This does not always happen. After trying out a few samples, I found if the line already contains line.separator, then its eol will be ^M. For example, {code:java} PrintWriter out = response.getWriter(); out.println("From " + System.getProperty("line.separator") + this); {code} {noformat} From test.TestServlet@180ab18^M {noformat} If line.separator is not used when constructing servlet output, then everything looks normal. My guess is the servlet container may first apply a dos-style eol, then does some sort of replacing with native eol by searching for the first occurrence of line.separator.
