SEVERE: releaseGUI to many times called

In some of my solutions that use the Smart Client, when I have the Java console up, I see this message, usually when loading a new form (the misspelling is not mine):

SEVERE: releaseGUI to many times called

Any ideas where this is coming from? Is it serious enough to address?

maybe a plugin calls that a few times to often
or you have some special construct that releaseGUI is called more often blockGUI but a solution itself (not counting maybe a plugin calling that) shouldn’t really be able to touch that.
