Build Identifier: 20100617-1415, M20100909-0800 I've tried this on both mac and win7 environments on relatively recent versions of Eclipse: Use Eclipse to introduce a parameter object (via refactoring menu). Next tell it to create a script of that refactoring, and it spits out a file with just xml and session tags. Upon investigation, I find this error: org.eclipse.core.runtime.CoreException: Error reading file %Path to my particular history file% at

copy it into a new script file and ask Eclipse to run it. Eclipse refuses to recognize it as a script file. Reproducible: Always Steps to Reproduce: 1.Use Eclipse to Introduce a Parameter Object (refactoring). 2.Tell it to create a script from that refactoring. 3.Watch it fail. 4.Retrieve refactoring manually from history file. 5.Try to apply this refactoring script. 6.Watch it fail again.
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
Still fails.
