External schema in directory with spaces cannot be read by JBossWS

Issue

• web archive (.war)
• WSDL found in WEB-INF/classes/wsdl/dir with spaces/wsdl.
• External schema in WEB-INF/classes/wsdl/dir with spaces/xsd.
• wsdlLocation defined as ./wsdl/dir with spaces/wsdl/service.wsdl

When deploying the application, I get an error:

Caused by: java.io.IOException: JBAS015526: Child './wsdl/dir with spaces/xsd/external.xsd' not found for VirtualFile: "/absolute/path/jboss-eap-6.1/standalone/deployments/myDeployment.war/"
