[Cucumber] Eclipse IDE compiler error, using io.cucumber.datatable.DataTableType

[Martin Tržický]

Hi,

I'm using 3.0.2 cucumber version and I cannot compile this particular code
in Eclipse (latest Neon, or Oxygen, Ubuntu):
DataTableType dtt = new DataTableType(Integer.class, (Map<String, String>
row) -> new Integer(0));

Stacktrace from Eclipse error log looks like:
java.lang.ArrayIndexOutOfBoundsException: 1

Has anyone struggled with this?
