Hi,
I just upgraded to dbvis 9.1 from version 8 and noticed that the new version (now running on Java 7, had 6 before) is causing my MacBook Pro (Late 2013) to switch to the discrete graphics. I have several other applications running on Java 7 (e.g. Eclipse) which do not cause this.
I think the JavaApplicationStub can possibly be exchanged against one that doesn't trigger this. Has anyone more insight?

Maik,
How do you determine that your MBP switch to discrete graphics when running DbVisualizer? I am looking for a way to reproduce this.

The most popular utility for this is [gfxCardStatus|http://gfx.io].
(uh, the forum seems to not recognize a url that short as one?)

Maik,
Thanks for the link.
I've verified the behavior and yes for Java 7 and 8 it switches to Discrete while running DbVisualizer and with Java 6 it stays with the Integrated. This is unfortunately managed by Java and I haven't found any option to control it. The following article may give some details:

Eclipse use another windowing toolkit (SWT) than DbVisualizer (Swing/AWT). That may explain why Eclipse doesn't cause the card change.
The best option for now seems to be gfxCardStatus and that Integrated Only is checked before starting DbVisualizer.

Re: dbvis 9 causes switch to discrete graphics on rMBP
I can confirm this happens on my machine as well. This is unfortunate because the discrete video card uses significantly more battery than the integrated. dbvis 7 did not have this issue, dbvis 9 does.
I like to keep dbvis running pretty much constantly and this makes it much more difficult to do so. Seems like this will cause a lot of issues for anyone running on a newer macbook.
