Subject [jira] [Commented] (DERBY-5543) include debug info in derby builds uploaded to maven
Date Thu, 15 Dec 2011 23:33:30 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13170580#comment-13170580
] 

Dag H. Wanvik commented on DERBY-5543:
--------------------------------------

I don't believe we want to make this the default download, since the "sane" version which
has line numbers complied in also has other instrumentation enabled and is significantly slower.
We could possibly install a debug version as well (with another name).
You can also download the debug jar files from the Apache site, of course, @ http://db.apache.org/derby/derby_downloads.html

> Looking at a strack trace from derby retrieved through maven, I see that derby is compiled
without debug information, this means line numbers are not available in stack traces,

> and it is harder to debug code by setting breakpoints within derby.  Derby deployed to
maven should have debug information included.  
> I'm not sure how this is controlled, but looking at pom.xml I see,

>     <sanity>insane</sanity>
> The default should be sane.
