Subject [jira] [Commented] (DERBY-6307) Improve the code coverage of org.apache.derby.iapi.services.info.JVMInfo
Date Mon, 26 Aug 2013 17:41:55 GMT

    [ https://issues.apache.org/jira/browse/DERBY-6307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13750292#comment-13750292

Myrna van Lunteren commented on DERBY-6307:

I agree that deferring testing of the javaDump() method is the right thing to do.
To document my findings: I tried to capture the output, but it appears the method causes the
IBM JVMs to send a request to the OS, which 1. is possibly different per OS and so gives possibly
different results per OS, and 2. prints out text that cannot be captured by System.out or
System.err. Perhaps if we'd call the method in a different process, but I think it all gets
too complex for the usage of the method.
The method is only used in two places (NetworkServerTestSetup, which I don't think counts
in the code coverage, and ContextManager, in the case of an error).
