For a code like:

import java.io.IOException;

class LambdaWithMultiCatch {
    public static void main(String[] args) {
        Runnable r = () -> {
        try {
            throw new IOException();
        } catch(IOException | IllegalArgumentException e) {
            System.out.println("This code will generate a wrong exception table");
        }
      };
      r.run();
    }
}

javac will generate an incorrect exception table for method main. The generated exception table will look like:

    Exception table:
         from to target type
             0 8 8 Class java/lang/Exception <---- no trace of IOException nor IllegalArgumentException

This is a known issue and developers should avoid using multi-catch statements inside lambda bodies till this issue is fixed.
