Fields display as null in debugger #9604

Closed stevemessick closed 9 years ago

stevemessick commented 11 years ago

Debugging in Dartium sometimes incorrectly displays fields as null. Yet there is an outline triangle to the left that can be opened to see the contents of the actual object. I have repeatedly been misled by this. Perhaps it would be possible to add an assertion to catch this inconsistency. Or at least flag it with an error to avoid misleading the programmer. //////////////////////////////////////////////////////////////////////////////////// Editor: 0.4.3_r20602 (2013-03-27) OS: Mac OS X - i386 (10.8.3) JVM: 1.6.0_43

Closing this out as there's not enough info to repro, and I believe there are a few related bugs open on the VM side. The current known cause of this is on a break-on-exceptions pause.

Added Duplicate label.

Removed this from the Later milestone. Added this to the M5 milestone.
