OWB on Google App Engine ?
Dear all,
does any of you use OWB on Google App Engine (GAE) ?
When I do (using latest stable 1.2), I get reflections related errors at
startup.
If any of you had a pom.xml for MyFaces 2.2 /OWB 1.2 (and ideally
Deltaspike 1.1) along with web.xml and other specific files, thanks in
advance,
Ludovic

or try to use Unsafe.getUnsafe() since that's available for java 7 applications.

sure, we are always happy about bug reports and even more about helping hands :)
I also hope you did like what you see when you did dig into OWB code-wise. We tried hard to not have people instantly get 'eye-cancer' when they look at it. But you know, it's a large codebase, so there is also room for improvement.

Well this was just a quick fix. A need more thoughts need to go into it to leverage other proxying logic possibilities. We will do this in trunk I think. For now it's really nice to have it running on GAE again. And as calls to Unsafe are not allowed on GAE, I fear there is other way than newInstance() to create proxies.
Please note that we usually only will create a single instance of each proxy and cache it! So it does not hurt that heavily as one might think.

I tested it and it seems to work. Thanks !
However, it seems to me that the SPI approach that you suggested first is
better. For complex objects, running the constructor everytime might be
significant performance hit. The newInstance way could be another
selectable implementation...

Hi!
Could you please checkout the latest branches/owb-1.2.x?
I implemented some fallbacks which get used when running on GAE now.
It basically boils down to not using Unsafe but newInstance() if we cannot get the allocate method from Unsafe. Of course this has some impact and might slow down your beans a bit, but it should work fine for now.

The problem is their Reflection policy ( in
https://cloud.google.com/appengine/docs/java/ )
«
Reflection
An application is allowed full, unrestricted, reflective access to its own
classes.
It may query any private members, call the method
java.lang.reflect.AccessibleObject.setAccessible(), and read/set private
members.
An application can also reflect on JRE and API classes, such as
java.lang.String and javax.servlet.http.HttpServletRequest. However, it
can only access public members of these classes, not protected or private.
An application cannot reflect against any other classes not belonging to
itself, and it can not use the setAccessible() method to circumvent these
restrictions.

I took a closer look at it and the root of the problem is the use of the
instance of sun.misc.Unsafe in
org.apache.webbeans.proxy.AbstractProxyFactory.
The method sun.misc.Unsafe#allocateInstance is retrieved by
AbstractProxyFactory#initializeUnsafe . This last method is a private
method, called by the constructor of AbstractProxyFactory.
As it is hard coded, a quick and dirty trick could be to shadow this
class, for example using the maven shade plugin to create a custom OWB
package, to replace the use of sun.misc.Unsafe#allocateInstance by
com.google.apphosting.api.ReflectionUtils#allocateInstance
Not very nice, not very evolutive, of course. I hope someone has a better
solution. :-)
A better way could be to have some kind of UnsafeAllocator hierarchy,
allowing one to provide custom methods for specific cases like this one.

Hi Ludovic!
Do you haven an example? I did run OWB on GAE a looong time ago, but did not test lately.
If you have a sample for us then we will make it work ;)
