Compile this program with gcj -g:
public class jmain
public static void main (String args)
There are five constructs with line numbers in the readelf -wi output (search for decl_line). The class jmain, the method main, and the synthetic constructor all have line number zero; they should be 1, 3, and not-sure-but-probably-1 respectively. The argument args is listed on line 5 instead of line 3 where it is declared in the source. The synthetic "this" argument to the synthetic constructor has line 1.

Closing as won't fix as the Java front-end has been removed from the trunk.
