[jboss-jira] [JBoss JIRA] (WFLY-7321) wrong parse of double quote in `\\"`

[Hisanobu Okuda (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13307749#comment-13307749 ] 

Hisanobu Okuda commented on WFLY-7321:
--------------------------------------

In org.jboss.aesh.parser.Parser.doesStringContainOpenQuote(), if a back-slash is ahead of the second double quote, it wrongly returns true even if a back-slash is escaped with another back-slash.
{code}
521     public static boolean doesStringContainOpenQuote(String text) {
522         boolean doubleQuote = false;
523         boolean singleQuote = false;
524         for (int i = 0; i < text.length(); i++) {
525             if (text.charAt(i) == SINGLE_QUOTE) {
526                 if (!doubleQuote &&
527                         (i == 0 || (i > 0 && !(text.charAt(i - 1) == BACK_SLASH))))
528                     singleQuote = !singleQuote;
529             }
530             else if (text.charAt(i) == DOUBLE_QUOTE) {
531                 if (!singleQuote &&
532                         (i == 0 || (i > 0 && !(text.charAt(i - 1) == BACK_SLASH))))
533                     doubleQuote = !doubleQuote;
534             }
535         }
536         return doubleQuote || singleQuote;
537     }
{code}
