build I20051012-1200 + JDTCore head

an AIOOBE occurs in SearchEngine#searchAllTypeNames when 'typeName' is an empty
array.

steps to reproduce
1) add the following test to JavaSearchTests

public void testCamelCaseTypePattern10() throws CoreException {
  TypeNameRequestor requestor =  new SearchTests.SearchTypeNameRequestor();
  new SearchEngine().searchAllTypeNames(
    "aa".toCharArray(),
    "".toCharArray(),
    SearchPattern.R_CAMELCASE_MATCH | SearchPattern.R_PREFIX_MATCH,
    TYPE,
    getJavaSearchScope(),
    requestor,
    IJavaSearchConstants.WAIT_UNTIL_READY_TO_SEARCH,
    null);
}

2) run this test
an exception occurs
