Hi,
this is a note to let you know that I've just added this patch to the
master-next branch of the meta-java repository at
git://git.yoctoproject.org/meta-java
As soon as it has gone through some more testing it will likely be
merged to the master branch.
If you have any questions, please let me know.
regards;Richard.L
