Tomcat 7 fails to start due to JDWP syntax error on Windows 7

Question

I am trying to get Tomcat 7 to run on my development machine at work. I have come across a really bizarre problem that I have never seen before.

When I run catalina run (as well as start), I get the following:

c:\apache-tomcat-7.0.59\bin>catalina run
Using CATALINA_BASE:   "c:\apache-tomcat-7.0.59"
Using CATALINA_HOME:   "c:\apache-tomcat-7.0.59"
Using CATALINA_TMPDIR: "c:\apache-tomcat-7.0.59\temp"
Using JRE_HOME:        "C:\Program Files\Java\jre7"
Using CLASSPATH:       "c:\apache-tomcat-7.0.59\bin\bootstrap.jar;c:\apache-tomcat-7.0.59\bin\tomcat
-juli.jar"
ERROR: JDWP option syntax error: -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n

artup.Bootstrap  start

c:\apache-tomcat-7.0.59\bin>

As you can see, we didn't ask it to use JDWP at all. I checked catalina.bat, and this code path should not even be executed, correct?

I have my JAVA_HOME set, and I've played with various configurations of JRE_HOME and so on.

This is so bizarre to me. How can I get Tomcat 7 to start?

EDIT:

c:\apache-tomcat-7.0.59\bin>echo %JPDA_OPTS%
%JPDA_OPTS%

c:\apache-tomcat-7.0.59\bin>
