JDK 9 RFR Fix bad javadoc link in javax.tools.JavaFileManager

[joe darcy]

Hello,

Please review the patch below to fix a bad javadoc link in 
JavaFileManager, listLocationsForModule*s* vs listLocationsForModule.

To avoid these problems in the future, I just sent out for review a 
build change to enable the doclint reference check for the java.compiler 
module.

Thanks,

-Joe
