Change subject: core: fixed gotcha in jdk8 streams ...................................................................... core: fixed gotcha in jdk8 streams code .findFirst().orElse(null) does NOT return first instance in stream or null. It returns first instance, if there's non-null first instance. It returns null if stream is empty. And throws NPE, when there's null valued instance in stream. Javadoc: /** * Returns an {@link Optional} describing the first element of this stream, * or an empty {@code Optional} if the stream is empty. If the stream has * no encounter order, then any element may be returned. * * <p>This is a <a href="package-summary.html#StreamOps">short-circuiting * terminal operation</a>. * * @return an {@code Optional} describing the first element of this stream, * or an empty {@code Optional} if the stream is empty * @throws NullPointerException if the element selected is null */ Change-Id: Ie15941484acb6eb0420bc55d72d5cbd9f3b5b1b2 Signed-off-by: Martin Mucha <mmucha(a)redhat.com&gt; --- M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/network/NetworkConfigurator.java A backend/manager/modules/bll/src/test/java/org/ovirt/engine/core/bll/network/NetworkConfiguratorTest.java 2 files changed, 60 insertions(+), 7 deletions(-) Approvals: Martin Mucha: Verified Jenkins CI: Passed CI tests Allon Mureinik: Looks good to me, approved Yevgeny Zaspitsky: Looks good to me, but someone else must approve -- To view, visit https://gerrit.ovirt.org/56646 To unsubscribe, visit https://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: Ie15941484acb6eb0420bc55d72d5cbd9f3b5b1b2 Gerrit-PatchSet: 5 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Martin Mucha <mmucha(a)redhat.com&gt; Gerrit-Reviewer: Allon Mureinik <amureini(a)redhat.com&gt; Gerrit-Reviewer: Jenkins CI Gerrit-Reviewer: Marcin Mirecki <mmirecki(a)redhat.com&gt; Gerrit-Reviewer: Martin Mucha <mmucha(a)redhat.com&gt; Gerrit-Reviewer: Tomas Jelinek <tjelinek(a)redhat.com&gt; Gerrit-Reviewer: Yevgeny Zaspitsky <yzaspits(a)redhat.com&gt; Gerrit-Reviewer: gerrit-hooks <automation(a)ovirt.org&gt;
