[jdk11u-dev] RFR: 8272342: [TEST_BUG] java/awt/print/PrinterJob/PageDialogMarginTest.java catches all exceptions

[Jonathan Dowland]

JBS: https://bugs.openjdk.java.net/browse/JDK-8272342

Please consider approving this for 11u. It's a test-only change. The test always passes prior to applying the patch, even if you deliberately supply invalid values. It also localizes the UI so, in my case, the test asks me to set a margin to 2 inches, but my localized UI lists the units in mm.

Patch applies clean. After applying, the UI is localized to US (so shows inches), passes if you follow the instructions, and fails if you do not, as it should.
