[Bug AWT/16731] New: GridBagLayout possibly slows down applications

[gcc-bugzilla at gcc dot gnu dot org]

Some Acunia tests which employ GridBagLayout tend to take a long time
to load.  Here's a list of such tests, but there may be others:

layout.BorderLayoutPositions
layout.CardLayoutPositions
layout.GridBagLayoutOverlay
layout.GridBagLayoutPositions
layout.GridBagLayoutRelative
layout.GridBagLayoutStacking

I'm not certain whether this is directly related to the GridBagLayout
class, since there are other tests which use GridBagLayout with over
dozen child components but still load relatively quickly.

The common thing between these tests is that they contain many
heavyweight components.  Simple instrumentation suggests that the
bottleneck occurs in the numerous addNotify() calls (one for each
heavyweight).  My guess is that this is due to JNI method call
overhead.  If that's true, I don't know how we can make it faster
other than to somehow streamline our native method calls so that they
execute faster.

OK, looks like we'll need to do some detailed profiling later.
