Hi all,

could you please review this small and trivial patch for whitebox and GetCodeHeapEntriesTest test? the test fails when run w/ AOT'ed java.base b/c WhiteBox::getCodeHeapEntries() returns null if there are no blob of the given type. the patch changes the method to return an empty array instead.

I've also fixed the test to correctly use Optional, before it used ::get() method which might throw NoSuchElementException exception, now it uses ::orElse(null) so we will get an error from the assertion at line #81 instead.

testing: GetCodeHeapEntriesTest.java test w/ and w/o AOT'ed java.base
