I am using eclipse Oxygen with scala ide 4.7

I suddenly started getting following error in pop ups when trying to run scala class with main method using Run As or Debug As dialogue:

"
Throwable during asyncExec
Malformed class name"

Next pop up after this tells me it is recommended to exit workbench. If I do it happens again upon restart of eclipse.

Following is log file content.

You're probably better to ask on the mailing for the technology you're using: http://scala-ide.org/docs/community.html#Mailing_lists

Perhaps Google "org.scala ide Malformed class name" and look at similar questions for possible answers.
