[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2849) DSLMappingEntryTest fails with Java 1.5 on hudson (but not in Java 1.6)

[ https://issues.jboss.org/browse/JBRULES-2849?page=com.atlassian.jira.plug... ] Geoffrey De Smet commented on JBRULES-2849: ------------------------------------------- I believe the usage of "?" in the regexes is wrong (which is causing the issue). For example: regex "(?<=\\W|^)-\\s*\\s+(.*?)\\s+is\\s+(.*?)$" The "?" means the character before me might or might not be there. so "ab?c" matches on "abc" and "ac" The "(" means start of a group. So "(?" should fail-fast (but it doesn't, just behave differently in jdk5 and jdk6). Also ".*?" should fail-fast: either you want ".*" (none or more) or ".+" (one ore more). -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
