I have been trying to run the eclipse's tests with harmony's classlib recently.
DRLVM or IBM VME? There are some tests will pass the string "-verify" to create a new VM.
For the reason mentioned by Oliver, all these tests failed because our launcher pass it directly to vm. It seems that the option "-verify" is widespread. So, i suggest to handle this specificly for -verify in our launcher.
If this incompatibility break applications like Eclipse, I think we have no choice but to be compatible, and I agree that this case should be fixed in launcher, because if one Harmony compatible VM complies with RI and spec on this -verify option, Harmony launcher should not break it. Would you please raise a jira on this? I'd like to look at it. 2007/2/16, Alexey Varlamov <[EMAIL PROTECTED]>:
