Hi, all: I now plan to make the self-host of Derby on Harmony. Is there anyone interested in this topic?
Here is what I encountered in the process. Hope it will be helpful to anybody who is interested in it. At first, the testcases even fails on RI both on windows and ubuntu and the result are different.??? After some struggiling, I have successfully passed the provided testcases on RI after I rebuild the source on my machine. But there still remains a problem: The derby team kindly rewrite the launcher for testcases in order to treat J9 vm differently if the property java.vm.name starts with "j9". But the j9 vm used in Harmony has been customized thus is different from traditional j9 vm that is expected by derby. This leads to failure to launch tests. I will talk on Derby's mailing list to find a solution. -- Leo Li China Software Development Lab, IBM
