My patch fixes the original problem: tests will fail instead, not
hang up.<br>
Printing extra debug info is a different story, and should require a
separate RFE.<br>
To print char[] addresses WhiteBoxAPI needs to be used, without it
only following data could be printed out:<br>
<br>
String 'DeduplicationTestString:7:XXXXXXXXXXXXXXXXXXXXXXXX' has
not deduplicated<br>
char1[]: [C@7ea987ac<br>
char2[]: [C@12a3a380<br>
<br>
but I think this is valueless.<br>
<br>
May be we can fix <br>

Thanks for looking!<br>
I love printing as much debug info as possible. But in this case
I have nothing to add.<br>
BTW, the deduplication tests are full of various
System.out.prinltn(), so I think the it will be enough
information in case of failure.<br>
<br>
I modified a little the code to make test fail. The jtr is
attached. Please let me know if you believe that more data need
to be printed.<br>

Yes, lots of output on failures. I looked for some output that
told<br>
me the addresses of the two strings (the two that don't verify)<br>
and the addresses of their char arrays. I couldn't find it. <br>
I think if I were debugging a failure, that's the first thing I
would<br>
want to see.<br>

If the test fails, can you print the strings with
System.out.println() or<br>
System.err.println()? Any information about the strings might
be<br>
useful to understand why deduplication didn't work or why the<br>
test thinks the deduplication didn't work (in case something<br>
happens that the test doesn't expect)? <br>

Hi, <br>
<br>
Would you please look at the simple fix of String
Deduplication tests. <br>
<br>
Description:<br>
<br>
When string deduplication has happened <i>s1.equals(s2)</i>
will be equivalent to <i>s1 == s2</i><br>
Deduplication is performed in a separate thread so it could
be delayed a bit.<br>
Tests are away about possible delay and give another chance
if deduplication hasn't <br>
happened by the moment of check.<br>
But tests wait for deduplication in infinitive loop, so if
deduplication doesn't work the tests <br>
will timeout, leaving hanging VM after. Which is not very
elegant.<br>
<br>
The fix is simple: replace infinitive loops with limited
ones and report failure.<br>
The logic of the tests hasn't changed. <br>
