[jira] Created: (HARMONY-2718) [classlib][drlvm] Simple test is
source of memory leak and uncaught OutOfMemoryError.
[classlib][drlvm] Simple test is source of memory leak and uncaught OutOfMemoryError.
-------------------------------------------------------------------------------------
Key: HARMONY-2718
URL: http://issues.apache.org/jira/browse/HARMONY-2718
Project: Harmony
Issue Type: Bug
Components: Classlib
Reporter: Pavel Afremov
Attachments: ZipDictionaryTest.java
The following test is source of memory leak (in classlib native code conceivably) and uncaught OutOfMemoryError.
import java.util.zip.Deflater;
public class ZipDictionaryTest {
private static final int MAX_ITERATION_NUMBER = 30000000;
private static final int PRINT_ITERATION_NUMBER = 500000;
private static final int DICTIONARY_SIZE = 100;
public static void main(String[] args) {
Deflater compresser = new Deflater();
byte[] dictionary = new byte [DICTIONARY_SIZE];
for (int i = 0; i < MAX_ITERATION_NUMBER;) {
System.out.println("Iteration = " + i);
for (int l = i + PRINT_ITERATION_NUMBER; i < l; ++i) {
compresser.setDictionary(dictionary,0,DICTIONARY_SIZE);
}
}
System.out.println("PASS");
}
}

-------------------------------------------
This issue is still reproducible on M4 release... (I've checked it on Windows x86, release build).

Nathan Beyer commented on HARMONY-2718:
---------------------------------------
If this is really a duplicate of HARMONY-2530, then it's invalid, as that bug is closed, but according to the comments, this bug is happening still. If that's true, then the 2530 should really be reopened.
Can someone else test this independently?
BTW - OutOfMemoryErrors should always be uncaught, at least by the JRE.

-------------------------------------------
This really looks like classlib issue - I've reproduced the failure in J9.
DRLVM output:
....
Iteration = 15500000
Iteration = 16000000
Uncaught exception in main:
java.lang.OutOfMemoryError:
at java.util.zip.Deflater.setDictionaryImpl(Deflater.java)
J9 output:
Iteration = 13500000
$echo $*
1
(ok, I've run it under cygwin).
