java.lang.IllegalAccessError when running with Spark 2.4.0

[amorskoy]

Before build I've changed spark version in pom.xml:
Spark-submit done in local[*] mode

<spark.version>2.4.0</spark.version>

java.lang.IllegalAccessError: tried to access class org.apache.spark.shuffle.sort.ShuffleInMemorySorter from class org.apache.spark.shuffle.sort.SplashUnsafeSorter

This error looks strange. These classes live in the same package. I check the code of spark 2.4.0, ShuffleInMemorySorter is a class with package-level visibility. We should be able to access this class.
I have also tried the tests with following command:

mvn package -Dspark.version=2.4.0

And it finishes successfully.
Would you please try the same command and see if you have any issues accessing this class?

@gmcaps - I am facing a similar issue as well, were you able to resolve this?

[amareshb]

@gmcaps I was able to solve the issue you mentioned by adding JAVA_HOME to path env variables.
