Hi, I am getting java.lang.AbstractMethodError after going to preferences of my plugin.

Here is part of stacktrace :

at com.intellij.openapi.options.ex.ConfigurableWrapper.enableSearch(ConfigurableWrapper.java:237)
	at com.intellij.openapi.options.SearchableConfigurable$Delegate.enableSearch(SearchableConfigurable.java:132)

Any idea why is that?
