screenshot1

during debuging i sometimes i only see "com.sun.jdi.ObjectCollectedException occurred while retrieving value" or "dealocated" in Expressions view.

The expression contained array and stream processing.

Arrays.stream(trees).map(et->et.toString()).collect(Collectors.joining(""+(char)10))

Was already fixed for variables view in bug 537399

Screenshot3 when expanding a node in the view

When expanding a node in the view the whole View sometimes goes berserk - not shown a list anymore (screenshot 3)
