Constructor NumberFormatException(GStringImpl (or String), Exception) does not exist

Also, typo in waitForPidsRemoved: intersection should be NON empty.

[1] Example seen: groovy.lang.GroovyRuntimeException: Could not find matching constructor for: java.lang.NumberFormatException(org.codehaus.groovy.runtime.GStringImpl, java.lang.NumberFormatException)
