When renaming a get-method in Eclipse, the warning "Be sure, may be you also should rename setter methods to avoid compilation problems." is displayed.
It should be possible to turn this warning off (and the sentence should be fixed).

By Googling the message, I found:
JBoss Tools SVN: r40216 - trunk/seam/plugins/org.jboss.tools.seam.core/src/org/jboss/tools/seam/core.

That is why I suppose the right component is seam.
