Subject: [PATCH] don't report exception if trying to update jar to the same
 file (this can happen if the version of the plugin is different from the
 version of the runtime it bundles; in that case, we've already messed up and
 there is no value in spamming EA with exceptions) (EA-73451 - IAE:
 KotlinRuntimeLibraryUtil.replaceFile)
