The on-line Sun docs for NoSuchMethodError state:
"Thrown if an application tries to call a specified method of a class (either static or instance), and that class no longer has a definition of that method.
Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed."
Have you tried to install different versions of EI? Particularly an older one over a newer one? You might try a complete uninstall and a fresh install, though that’s a pain.
Double-check that you have the supported Java environment that’s specified in the install docs for the version you’re installing.
