Since Hudson 1.357 this function will fail:

private String getFullPath(FilePath fp) {
FilePath parent = fp;
String path = "";
try {
while (parent.exists())

{ path = parent.getName() + File.separator + path; parent = parent.getParent(); path = File.separator + path; }

} catch (IOException ex)

{ Logger.getLogger(UpdateMatrixProperty.class.getName()).log(Level.SEVERE, null, ex); } catch (InterruptedException ex) { Logger.getLogger(UpdateMatrixProperty.class.getName()).log(Level.SEVERE, null, ex); }

return path;
}
with this error on the "parent = parent.getParent();" line:

FATAL: String index out of range: -1
