Administration console - improve error messages when executing script

When executing javascript which results in error, the error message displayed by Administration console is not very helpful:
Error Some unexpected problem happened when launching the task: DGISPN0118: Failed to invoke operation: ISPN026003: Script execution error

Executing the same script through hotrod client throws more descriptive exception:
ReferenceError: "console" is not defined in <eval> at line number 4

The script is:
console.debug("test");
