I worked in Oracle SOA product(BPEL) for 2 years. We had to do migration from 10g to 11g because Oracle wasn't supporting 10g version anymore. While migrating we came across a lot of issues that worked fine with 10g but failed in 11g. So we raised a lot of service requests with Oracle. Most of those got rejected by Oracle as they were not high priority meaning there were terrible workarounds existing for them. They only bothered fixing those ones without which we can't work(I guess they had to or my company would have sued Oracle). We ended up writing a lot of horrible work around just to make existing code work. Yes we did not reverse engineer that code even though I feel it would have done lot of good for us. Not to mention the tool set provided by Oracle is utter crap as in it barely works on its own. So I am not at all surprised that Oracle have that kind of mentality here. In all our communications with Oracle I felt they never really actually cared for what we the customers really want. All they actually care about it protecting their investments.
