My "problem" is that it's set correctly and I want to break it, but can't figure out where it's getting set in the first place.
I can see several places where $DISPLAY is referenced but at the point that the dollar sign is in front it's already an environment variable(I think).

jhat(1) General Commands Manual jhat(1)
NAME
jhat - Java Heap Analysis Tool
SYNOPSIS
jhat [ options ] <heap-dump-file>
PARAMETERS
options
Options, if used, should follow immediately after the command name.
heap-dump-file
Java binary heap dump file to be browsed. For a dump file that contains multiple heap dumps, you may specify which dump in the file by
appending "#<number> to the file name, i.e. "foo.hprof#3".
DESCRIPTION
The jhat command parses a java heap dump file and launches a webserver. jhat enables you to browse heap dumps using your favorite web-
browser. jhat supports pre-designed queries (such as 'show all instances of a known class "Foo"') as well as OQL (Object Query Language) -
a SQL-like query language to query heap dumps. Help on OQL is available from the OQL help page shown by jhat. With the default port, OQL
help is available at http://localhost:7000/oqlhelp/
There are several ways to generate a java heap dump:
* Use jmap -dump option to obtain a heap dump at runtime;
* Use jconsole option to obtain a heap dump via HotSpotDiagnosticMXBean @
http://java.sun.com/javase/6/docs/jre/api/management/extension/com/sun/management/HotSpotDiagnosticsMXBean.html at runtime;
* Heap dump will be generated when OutOfMemoryError is thrown by specifying -XX:+HeapDumpOnOutOfMemoryError VM option;
* Use hprof @
http://java.sun.com/developer/technicalArticles/Programming/HPROF.html.
NOTE: This tool is experimental and may not be available in future versions of the JDK.
OPTIONS
-stack false/true
Turn off tracking object allocation call stack. Note that if allocation site information is not available in the heap dump, you have to
set this flag to false. Default is true.
-refs false/true
Turn off tracking of references to objects. Default is true. By default, back pointers (objects pointing to a given object a.k.a refer-
rers or in-coming references) are calculated for all objects in the heap.
-port port-number
Set the port for the jhat's HTTP server. Default is 7000.
-exclude exclude-file
Specify a file that lists data members that should be excluded from the "reachable objects" query. For example, if the file lists
java.lang.String.value, then, whenever list of objects reachable from a specific object "o" are calculated, reference paths involving
java.lang.String.value field will not considered.
-baseline baseline-dump-file
Specify a baseline heap dump. Objects in both heap dumps with the same object ID will be marked as not being "new". Other objects will
be marked as "new". This is useful while comparing two different heap dumps.
-debug int
Set debug level for this tool. 0 means no debug output. Set higher values for more verbose modes.
-version
Report version number and exit.
-h
Output help message and exit.
-help
Output help message and exit.
-J<flag>
Pass <flag> to the Java virtual machine on which jhat is run. For example, -J-Xmx512m to use a maximum heap size of 512MB.
