Bug 32714 Packages View: flickering and loosing expanded state when logical package is selected with hierarchical layout
In the java browsing perspective: - enable hierarchical layout for the packages view - select a logical package in the packages view - select types/methods in the types/methods views -> the packages view flickers and looses the expanded state (the tree is only expanded upto the logical package, other expanded subtrees are collapsed)
