In KDE 11.10, System Settings->Application Appearance->Colors(on left)->Colors(tab)->Color Set->Tooltop->Normal Background. Mine was set to black, resulting in black on black in Eclipse.

It might be too late. But I think you need to change this from your OS.
System->Preference->Appearance->Customise->Colors->Tooltips
solved my problem.
I am using Ubuntu 10.04.
In ubuntu (software center) find and Install GNOME Color Chooser application and set Tool Tip Background color (yellow). Set foreground color to black if you find color viewing problem on other tooltips.
If you want to change the colour of the hover over for a method that indicates you can click through to its declaration:
Preferences > General > Editors > Text Editors
There is a list of options in 'Appearance Color Options' in the right panel. Select the 'Hyperlink' option and change its colour.
