Java unable to find class when executed via PHP, identical command works in CLI

I'm attempting to run a small Java class from within a PHP script. It works as expected on Linux, but when the same script is executed on Windows I receive:

Could not find or load main class JDBCProxy

Here's the relevant PHP:

$classpath = join(PATH_SEPARATOR, array(
    dirname(__FILE__).DIRECTORY_SEPARATOR.'JDBCProxy',
    dirname(__FILE__).DIRECTORY_SEPARATOR.'JDBCProxy'.DIRECTORY_SEPARATOR.'libs'.DIRECTORY_SEPARATOR.'json-simple-1.1.1.jar',
));

$cmd = sprintf("java -cp '%s' JDBCProxy", $classpath);

...

$process = proc_open($cmd, $descriptorspec, $pipes);

The output of sprintf is 

java -cp 'C:\worker\lib\DB\JDBCProxy;C:\worker\lib\DB\JDBCProxy\libs\json-simple-1.1.1.jar' JDBCProxy

When run directly from the command line, this works as expected. Why isn't Java able to locate the class when run from the context of PHP?

For Windows, use double quotes (") instead of single ones (').

See Including all the jars in a directory within the Java classpath for Java specifics and this answer for Windows' treatment of single quotes.
