Date Mon, 30 Oct 2006 17:14:23 GMT
    [ http://issues.apache.org/jira/browse/HARMONY-1904?page=comments#action_12445659 ] 
Alexei Fedotov commented on HARMONY-1904:

The bug can possibly affect class library test runs, see http://wiki.apache.org/harmony/Unit_Tests_Pass_on_DRLVM

Here is an explanation what shulf be fixed in DRLVM:

A separate issue should be opened against class library to process EINTR return code of hysock_select()
correctly (try again).
