Subject [jira] [Commented] (DERBY-5519) Update code in JVMInfo#derbyVMLevel to give correct results for Java 7 and provisionally for 8.
Date Mon, 05 Dec 2011 16:32:39 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162866#comment-13162866
] 

Dag H. Wanvik commented on DERBY-5519:
--------------------------------------

Another thing is, what JDBC level should be reported above? It seems we should return JDBC
4.1, at least with Java 6 and 7.

> The method derbyVMLevel gives correct result only up to and including Java 6, cf. this
snippet:
> public static String derbyVMLevel()
> {
>     switch (JDK_ID)
>     {
>     case J2SE_14: return J2ME ? "J2ME - JDBC for CDC/FP 1.1" : "J2SE 1.4 - JDBC 3.0";
>     case J2SE_142: return "J2SE 1.4.2 - JDBC 3.0";
>     case J2SE_15: return "J2SE 5.0 - JDBC 3.0";
>     case J2SE_16: return "Java SE 6 - JDBC 4.0";
>     default: return "?-?";
>     }
> }
> This is exposed through our MBean implementation in org.apache.derby.jdbc.JDBC#getDriverLevel
