SEVERE: Memory leak from Tracer.ThreadTrace when setTracerMode is set to OFF.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Disable your tracer via  
options.setTracerMode(CompilerOptions.TracerMode.OFF);      
2. Run compiler in a Java project.
3. Stop Tomcat 7 server.
4. View logs:

SEVERE: The web application [/translator] created a ThreadLocal with key of 
type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@62add0e8]) and a 
value of type [com.google.javascript.jscomp.Tracer.ThreadTrace] (value []) but 
failed to remove it when the web application was stopped. Threads are going to 
be renewed over time to try and avoid a probable memory leak.

4. MaxPermSize JVM setting helps mask the issue, but over time we have gotten 
OutOfMemory exceptions on our development and staging servers.

What is the expected output? What do you see instead?
No errors or memory leaks should be expected output, because the tracer should 
be disabled.

What version of the product are you using? On what operating system?
closure-compiler r1811
