Java Class Cast Exception

[dmelloreema]

Hi,
I am using the datasetutils and am receiving the following error message. I tried the earlier of datasetutils-37 which also produced the same error message.

" java.class.path:datasetutils-39.0.1.jar
SystemClassLoader:Exception in thread "main" java.lang.ClassCastException: java.base/jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to java.base/java.net.URLClassLoader
at com.sforce.dataset.DatasetUtilMain.printClasspath(DatasetUtilMain.java:1204)
at com.sforce.dataset.DatasetUtilMain.main(DatasetUtilMain.java:79)"

I appreciate any help/guidance.

Thanks!

@dmelloreema What version of Java are you using? Java 8 or 9? I've had this issue before and Java 9 appears to break it. Uninstall Java 9 and downgrade to whatever the latest version of 8. I believe it's 1.8.162.
