Fix possible InaccessibleObjectExceptions during debugging session #7633

Closed mbien closed 1 month ago

mbien commented 1 month ago

Opening the popup table during a breakpoint for a variable can cause reflection exceptions due to JDK module encapsulation.

e.g for a java.util.Date field: image click on the > symbol

java.lang.reflect.InaccessibleObjectException: Unable to make field long sun.util.calendar.BaseCalendar$Date.cachedFixedDateJan1 accessible: module java.base does not "opens sun.util.calendar" to unnamed module @493e76e4
