1- onFail action is missing
2- These need to be 2 separate changesets each inserting a single row
3- column name in where clause should be java_class_name and not java_class

I have addressed  all the above issues at https://github.com/wluyima/openmrs-core/commit/ccfb5e1a87dfb44654a35564d051cfa7bd71f194
