------------------------------------
Besides above error, there are another errors with scala-2.12
{code}
/home/zly/prj/oss/jdk9_HOS_SOURCE/spark_source/core/src/test/scala/org/apache/spark/util/ClosureCleanerSuite.scala:151:
reflective access of structural type member method getData should be
enabled
by making the implicit value scala.language.reflectiveCalls visible.
64275 This can be achieved by adding the import clause 'import
scala.language.reflectiveCalls'
64276 or by setting the compiler option -language:reflectiveCalls.
64277 See the Scaladoc for value scala.language.reflectiveCalls for a
discussion
64278 why the feature should be explicitly enabled.
