The Java debugger API dies while dumping (ie printing the fields of) classes with
static final String fields.

Given the following java code, the debugger API will exit abruptly when it tries to
get the value of the field. Sometimes I got a message (from my debugger) that said
"Received sigchild for 698 exit=6".

======== Java Source ===========
class StaticStress {
// this is a stripped down version of sun.tools.debug.AgentConstants
static final String PSWDCHARS = "23456789abcdefghijkmnpqrstuvwxyz";
}

======== jdb Transcript =========

load StaticStress
0xee30c4d8:class(StaticStress)
> dump 0xee30c4d8
0xee30c4d8 = 0xee30c4d8:class(StaticStress) {
    superclass = 0xee300018:class(java.lang.Object)
    loader = null

    static final String PSWDCHARS =
The communications channel closed.
===============================

In my debugger, the debugger API dies when I call:
  realValue.getFieldValue(index);
where realValue is a remoteObject. for the StaticStress class.
