> NullPointerException in RPackageUtils#checkManifestForR

> URL: https://issues.apache.org/jira/browse/SPARK-20815
> Project: Spark
> Issue Type: Bug
> Components: SparkR
> Affects Versions: 2.1.1
> Reporter: Andrew Ash
> Fix For: 2.2.0, 2.3.0
>
>
> Some jars don't have manifest files in them, such as in my case
> javax.inject-1.jar and value-2.2.1-annotations.jar
> This causes the below NPE:
> {noformat}
> Exception in thread "main" java.lang.NullPointerException

> due to RPackageUtils#checkManifestForR assuming {{jar.getManifest}} is
> non-null.
> However per the JDK spec it can be null:
> {noformat}
> /**
> * Returns the jar file manifest, or <code>null</code> if none.
> *
> * @return the jar file manifest, or <code>null</code> if none
> *
> * @throws IllegalStateException
> * may be thrown if the jar file has been closed
> * @throws IOException if an I/O error has occurred
> */
> public Manifest getManifest() throws IOException {
> return getManifestFromReference();
> }
> {noformat}
> This method should do a null check and return false if the manifest is null
> (meaning no R code in that jar)
