Parser error if JS file has shebang (#!)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. specify shebang like "#!/usr/bin/env node" in test.js file
2. run closure-compiler with it
3. it files with the following error.
"test.js:1: ERROR - Parse error. primary expression expected
#!/usr/bin/env node"

What is the expected output? What do you see instead?
I expect it could succeed

What version of the product are you using? On what operating system?
lastest version

Please provide any additional information below.

You forgot the opening " in the string literal.

Thanks for comment. I did'n know this.
Does it have to specify with Quote(") to write shebang in JS script file  ?

(Invalid)
#!/usr/bin/env node

(Valid)
"#!/usr/bin/env node"

Hmm.. after wrapping it with the quota, it doesn't work properly..

When it has shebang in the first line on JS file, it works although not 
specifying node.
./test.js ( O )
this works fine like "node ./test.js"

But after wrapping it with quote, it does not work properly.
./test.js (X)
line 1: #!/usr/bin/env node: No such file or directory

"Contents of test.js"

#!/usr/bin/env node
var test = "normal ?"
console.log("Is this", test);

#!/usr/bin/env node

is not valid JavaScript, that's why you're getting a parse error.
