[Bug java/33023] New: throw null

[mark at gcc dot gnu dot org]

gcj (GCC) 4.1.2 20070626 (Red Hat 4.1.2-13)

public class n
{
  public static void main(String[] args)
  {
    throw null;
  }
}

$ gcj -C n.java
n.java: In class 'n':
n.java: In method 'n.main(java.lang.String[])':
n.java:5: error: Checked exception ‘null’ isn't thrown from a ‘try’ block.
    throw null;
       ^
1 error

This is allowed according to JLS 14.18 "throw Expression ; [...] f evaluation
of the Expression completes normally, producing a null value, then an instance
V' of class NullPointerException is created and thrown instead of null."

This is with the old source frontend, with the new frontend based on ecj, this
does compile correctly.
