[oe] [meta-java][PATCH v2] icedtea: disable error format-overflow for gcc 7

[Richard Leitner]

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
