When using a directory with blanks in the name, building Apache POI fails:

compile-ooxml-lite:
     [java] Collecting unit tests from /opt/jenkins/workspace/Apache
     [java] Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: -1
     [java] 	at java.lang.String.substring(String.java:1937)
     [java] 	at java.lang.String.substring(String.java:1904)

     [java] 	at org.apache.poi.util.OOXMLLite.main(OOXMLLite.java:78)
     [java] Java Result: 1

The step for "compile-ooxml-lite" is currently written in a way that does not support blanks, the following patch fixes this:
