Nicholas Dzwill commented on IGNITE-1493:
-----------------------------------------
I see that issue IGNITE-1526 is scheduled for release 1.5, is there any work
being done with regard to the usage of Unsafe in the 1.4 release? We are
hoping to get a stable version of the product to use in our HP-UX environments
in the near future.
We are also working with HP on this issue to see if can be supported by the JDK
but have made no progress on that front yet.
Thank you for any update you can give me.

> Key: IGNITE-1493
> URL: https://issues.apache.org/jira/browse/IGNITE-1493
> Project: Ignite
> Issue Type: Bug
> Components: data structures
> Environment: * HP-UX B.11.31 IA64W machine
> * JRE version: Java(TM) SE Runtime Environment (7.0) (build
> 1.7.0.14-jinteg_2015_08_07_03_06-b00)
> * Java VM: Java HotSpot(TM) Server VM (24.85-b05-jre1.7.0.14-rc1 mixed mode

> A fatal exception is thrown during queue instantiation when using an HP-UX
> B.11.31 IA64W machine.
> The environment is as follows:
> * JRE version: Java(TM) SE Runtime Environment (7.0) (build
> 1.7.0.14-jinteg_2015_08_07_03_06-b00)
> * Java VM: Java HotSpot(TM) Server VM (24.85-b05-jre1.7.0.14-rc1 mixed mode
> hp-ux-ia64 )
> The error logged is as follows:
> * Current thread (01ab2800): JavaThread "main" [_thread_in_vm, id=23,
> lwp_id=3525570, stack(4e501000,4e601000)]
> * siginfo:si_signo=SIGBUS: si_errno=0, si_code=1 (BUS_ADRALN),
> si_addr=5e038d15
>
> The exception above means there is an "invalid address alignment" (writing to
> an odd memory location) when calling the following method:
> * Class: org.apache.ignite.marshaller.optimized.OptimizedObjectOutputStream
> * Method:
> {code:borderStyle=solid}
> /** {@inheritDoc} */
> @Override public void writeInt(int v) throws IOException {
> requestFreeSize(4);
> UNSAFE.putInt(bytes, byteArrOff + off, v); // byteArrOff + off =
> 17 when this exception is thrown
> onWrite(4);
> }
> {code}
>
> Basic setup - Ignite is configured with spring and pushed to the constructor
> of a class. That class uses this instance of Ignite to instantiate an
> IgniteQueue as follows:
> {code:borderStyle=solid}
> CollectionConfiguration configuration = new CollectionConfiguration();
> configuration.setCollocated(true);
> IgniteQueue<String> queue = ignite.queue("queue", 0, configuration);
> {code}
>
> Partial stack:
> * Instantiating the queue calls:
> **
> org.apache.ignite.internal.processors.datastructures.DataStructuresProcessor.compatibleConfiguration()
>
> * Which in turn calls:
> ** org.apache.ignite.internal.processors.cache.GridCacheAdapter.invoke()
> * Leading to the fatal error when calling:
> **
> org.apache.ignite.marshaller.optimized.OptimizedObjectOutputStream.writeInt()
> The error log has been attached with the stack trace of the error. The
> server log is also attached. We are running Ignite in a variety of
> environments and this issue only appears to exist in this specific
> environment and is consistently hit in the same place with no apparent
> work-around.
