Subject [jira] [Commented] (DERBY-1046) JVMInfo is duplicated in derbyclient.jar
Date Wed, 28 Sep 2011 13:03:45 GMT

    [ https://issues.apache.org/jira/browse/DERBY-1046?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13116411#comment-13116411
] 

Knut Anders Hatlen commented on DERBY-1046:
-------------------------------------------

Perhaps we could just remove that line from the sysinfo output to avoid having to maintain
duplicated code? Before, it used to tell exactly what Derby recognized the current platform
as and which JDBC level it was running at. Now, it just tells what sysinfo thinks the engine
recognized the platform as, and that information could just as easily and reliably be taken
directly from the Java Information section of the sysinfo output.

There's a small typo in the patch: The Java SE 7 string lacks a hyphen (for consistency with
the other versions).

> The JVMInfo class is included twice in derbyclient.jar, as
> org.apache.derby.iapi.services.info.JVMInfo and
> org.apache.derby.shared.common.info.JVMInfo. The only one of them
> actually used by the client code is the one found in
> org.apache.derby.shared.common.info.
> org.apache.derby.iapi.services.info.JVMInfo is also included in
> derby.jar, so one could run into problems if the classpath contains
> derbyclient.jar and derby.jar with different versions.
