Eclipse doesn't recognize smartcardio library

Question

After migration from Sun's jdk (1.8) to Openjdk12 - Eclipse does not recognize the whole library of "javax.smartcardio".

for example:

import javax.smartcardio.Card; 

will cause the errors

Card cannot be resolved to a type

The import javax.smartcardio cannot be resolved

We've tried to add the "src.zip" to the JRE coniguration in the Eclipse, but its content does not appear in "Project Explorer"...
