The difference between HW vs LW popups are not only in the performance,
there is a difference in the appearance. The LW popups inherit the visual properties such as
translucency/opacity from the owner window(since the painted on the owner), while HW popup are independent from the owner.
When we break this functionality in JDK 7 we got a regression report:
https://bugs.openjdk.java.net/browse/JDK-7156657

Current bug report is not a testbug, and I do not see a reason why the test should be updated.
Even if we add workaround to the test then we will need to create a new CR to check this behavior later, but why wee need to do it, since we already have this bug, which mentions this issues already.

The common workflow for such product issues is to add it to the "problem list" using the product bugid.
