PDF module produces unordered error messages

[Chris Hillery]

When something goes wrong with the PDF module, the stack trace is printed before the error message, leaving the error message pointing at nothing. eg:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no read-pdf_1.0 in java.library.path
 at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1856)
 at java.lang.Runtime.loadLibrary0(Runtime.java:845)
