Building against java-1.5.0-gcj-devel instead of java-1.6.0-openjdk-devel

[Richard Fearn]

Hi,

I'm building jcip-annotations for x86_64 rawhide using mock on my F14
x86_64 laptop. The package BuildRequires java-devel >= 1.5.0 and
java-1.6.0-openjdk-devel is being installed to satisfy that
dependency.

When requesting a scratch build, such as this one:

  http://koji.fedoraproject.org/koji/taskinfo?taskID=2694190

java-1.5.0-gcj-devel is installed instead. Anyone know why? I expected
the latest version to be used for the Koji build.

Also, has anyone noticed that the GCJ javadoc produces an empty
package-list file? For example, this recent build of jcip-annotations:

  http://koji.fedoraproject.org/koji/buildinfo?buildID=207525

resulted in this rpmlint output:

 
http://autoqa.fedoraproject.org/results/32774-autotest/qa02.c.fedoraproje...

Note the "zero-length
/usr/share/javadoc/jcip-annotations/package-list" error. That file
should contain "net.jcip.annotations".

Regards,

Rich

I think it is because yum uses package name length in this case (for lack of 
any better information) to pick between java-1.5.0-gcj-devel and 
java-1.6.0-openjdk-devel.  They both satisfy java-devel >= 1.5.0 so in theory 
either should be fine.

Orion is right in that either should be fine because both satisfy that
requirement, but I too have found javadoc generation to be
particularly flakey with GCJ.

In order to work around this, I think it is ok to BuildRequire
java-devel >= 1:1.6.0 as long as you build with source=1.5 and
target=1.5.
