this code compiles since 7:
public void m(){
        try{
            System.out.println();
        } catch (Throwable e) {
            throw e ;
        }
    }


and this already not:
    public void m(){
        try{
            if(false) throw new MyCheckedException();
        } catch (Throwable e) {
            throw e ;
        }
    }
    public static class MyCheckedException extends Throwable {}

javac checks try body for code which contains statements(methods) with checked exceptions, if they doesn't contain this . But Exception table still contains Throwable:


  public void m();
      stack=1, locals=2, args_size=1
         0: getstatic #5 // Field java/lang/System.out:Ljava/io/PrintStream;
         3: invokevirtual #6 // Method java/io/PrintStream.println:()V
         6: goto 12
         9: astore_1
        10: aload_1
        11: athrow
        12: return
      Exception table:
         from to target type
             0 6 9 Class java/lang/Throwable
      StackMapTable: number_of_entries = 2
        frame_type = 73 /* same_locals_1_stack_item */
          stack = [ class java/lang/Throwable ]
        frame_type = 2 /* same */
