Subject [jira] Commented: (DERBY-3782) Client Configuration.java imports engine class org.apache.derby.iapi.services.info.JVMInfo
Date Thu, 18 Sep 2008 21:06:44 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12632387#action_12632387

Myrna van Lunteren commented on DERBY-3782:
-------------------------------------------

After playing with this for a while, I realized that even when we don't need the services.info.JVMInfo
from the Configuration class, it's still getting included in derbyclient.jar because it's
used in the sysinfo calls from the client.

I personally like approach a better, for otherwise, we get 2 JVMInfo classes in derbyclient.jar.
But, as the JVMInfo class is getting included anyway, maybe we should not fix this issue.

Or is there a better approach to addressing this?

> The client code (org.apache.derby.client.am.Configuration) imports the engine class org.apache.derby.iapi.services.info.JVMInfo.
> This will make two copies of the class in derby.jar and derbyclient.jar which can cause
problems if mixed version jars are used and  I think may cause jar sealing issues as well.
> Until we have a good framework for sharing code between engine and client, the client
shouldn't import engine classes.
