PAXSB-68 - BndUtils swallowing exception when bundle not generated

Fix for this issue. The line endings were for Windows on this file I think so the diff looks like I replaced the whole file :) I'm essentially just changing this:

                catch( IOException e )
                {
                    LOG.warn( "Bundle cannot be generated" );
                }

to

                catch( IOException e )
                {
                    LOG.warn( "Bundle cannot be generated", e );
                }
