29426012 introduced an NPE.
If a project implements Queue.FlyweightTask, build.getExecutor() returns null.
This prevents any flyweight build from finishing successfully.

[JENKINS-17016] Fix Spanish translations
Thanks

Correct Spanish grammar and orthography in various Spanish translation
files.

The compiler used to compile src/test/java/**/*.groovy seems to produce
a reference to org.codehaus.groovy.transform.powerassert.ValueRecorder,
while our Groovy runtime appears to contain
org.codehaus.groovy.runtime.powerassert.ValueRecorder.

I suppose the proper fix is to somehow run Groovy 1.8 compiler,
but this fix adds the necessary code to the classpath.

Added backward compatible data loader and a corresponding test case.

HyperlinkNote shouldn't emit the absolute URL.

This change is originally from pull request #682.

For a reason similar to ded37a2b,
better to run with non empty context path.

This helps us catch a typical error of not using ${rootURL} or
getContextPath() where needed.

[JENKINS-15156] Missing call to onCreatedFromScratch caused failures in MatrixProjectTest (when run from Surefire at least).

d62e95a9.

b5ed3199 already caught linkage errors but then unconditionally returned false from Util.isSymlink, which is wrong;
we want to fall back to the generic File.canonicalPath comparisons in this case.

Add run display name as an environment variable when RunParameter is used as a parameter.

Url with contextPath for non-standalone installs.

There are several incompatibilities in XStream 1.4 that resulted in our
changing the core, but according to the text search on all the public
plugins, none of these changes affect the 600+ plugins we have today.

However, it is still possible that there are some parts of XStream 1.3
that plugins depend on but the core doesn't depend on --- we won't be
able to tell those problems at this point.
