RFR: 8335231: [macos] Test java/awt/print/PrinterJob/Cancel/PrinterJobCancel.java failed on macOS because the case didn't get the expected PrintAbortException [v5]

[Prasanta Sadhukhan]

> When a printjob is cancelled midway, `PrinterAbortException `was not thrown in macos. because 
> firstly,` cancelCheck` invokes` LWCToolkit.invokeLater` with null as parameter causing it to fail with NPE and
> secondly PrinterAbortException was consumed silently when `printLoop` throws any exception
> which is rectified to throw the PrinterAbortException when encountered..

Prasanta Sadhukhan has updated the pull request incrementally with one additional commit since the last revision:

  Dont call completePrintLoop if cancelDoc is called as both exits PrintingLoop
