1. WARNING in /src/org/eclipse/e4/tools/compatibility/migration/tests/E4MigrationToolTest.java
(at line 90)
MElementContainer<MPerspectiveStack> windowContainer =
(MElementContainer<MPerspectiveStack>)mWindowElement;
Type safety: Unchecked cast from MWindowElement to
MElementContainer<MPerspectiveStack>
As it's test code it's fine to cast thus suppress warning.
Some other minor code improvements done too.
