[Ikvm-developers] IKVM.NET with Spring

[P***@nomura.com]

Hi folks,

I am looking for help on using IKVM with the spring framework. We are using the ‘one large DLL’ solution to compile a large number of our libraries. We recently added the spring framework to these.

Compiling everything together with ikvmc works but on initialization of the spring framework, the ikvm class loader behaves differently than the class loader of the standard JVM. The class loader of the standard JVM tolerates that some extensions of the spring framework are missing, whereas the ikvm class loader throws an exception:

"ClassNotFoundException: com.datastax.driver.core.Cluster$Builder\r\n at IKVM.Internal.ClassLoaderWrapper.LoadClass(String name, LoadMode mode)\r\n at IKVM.Internal.ClassLoaderWrapper.LoadClassByDottedName(String name)\r\n at IKVM.Internal.CompiledTypeWrapper.get_InnerClasses()\r\n at IKVM.StubGen.StubGenerator.WriteClass(Stream stream, TypeWrapper tw, Boolean includeNonPublicInterfaces, Boolean includeNonPublicMembers, Boolean includeSerialVersionUID, Boolean includeParameterNames)\r\n at IKVM.Internal.VirtualFileSystem.VfsAssemblyClass.Populate()\r\n at IKVM.Internal.VirtualFileSystem.VfsAssemblyClass.Open()\r\n at IKVM.Internal.VirtualFileSystem.Open(String name, FileMode fileMode, FileAccess fileAccess)\r\n at Java_java_io_FileDescriptor.open(String name, FileMode fileMode, FileAccess fileAccess)\r\n at java.io.FileDescriptor.open(String , FileMode , FileAccess )\r\n at java.io.FileDescriptor.open(String , Int32 , Int32 )\r\n at java.io.FileDescriptor.openReadOnly(String )\r\n at Ja

Here are the detail of our setup:
IKVM 8.1
Spring 4.3.2.RELEASE
Spring boot 1.4.0.RELEASE
Target .NET 4

We are using the statement “ikvm.runtime.Startup.addBootClassPathAssembly(Assembly.Load("OurLargeAssembly"));”. We are not using any –classloader argument in the args of ikvmc.

We tried downloading the datastax driver and adding it to our large assembly. It worked, but right after we faced the same problem with ‘elasticsearch’. But this time, adding this package caused an ikvmc crash:

warning IKVMC0100: Class "org.jboss.netty.bootstrap.ServerBootstrap" not found
warning IKVMC0100: Class "org.jboss.netty.channel.socket.nio.NioServerSocketChannelFactory" not found
warning IKVMC0100: Class "org.jboss.netty.channel.group.ChannelGroup" not found

It look like that your framework try to access the stream of
com.datastax.driver.core.Cluster$Builder.class. Because class resources
are not available IKVM that it try to generate a stub of the stream
which is failing. If this is the case then it look like a bug in IKVM.

Which version of IKVM do you use?

Hi Volker,

This sounds similar to something I am seeing. In our app, we sometimes push
updated classes to a server. This does not work from the ikvmc DLL. I had
thought it might be another pathing issue, but it sounds more like what
you're mentioning here.

This is how we are loading class definitions for packaging and push:

InputStream inStream = classLoader.getResourceAsStream(path);


Am I correct in understanding that we'll need to use a more generic file
stream, instead, to load the classes under IKVM?

Thanks,
Paul

Hi Paul,

What do you want do? There does not exists Java classes in the .NET
world. Your Java classes was compiled to .NET IL code.

Illumon - Big Value From Big Data

[Paul Chambre]

This isn't for use at the client side. This is to upload classes from the
client to the server to use at the server side... The server is, and will
always be, a Java process.

Post by Volker Berlin
Hi Paul,
What do you want do? There does not exists Java classes in the .NET world.
Your Java classes was compiled to .NET IL code.
Volker
Hi Volker,
This sounds similar to something I am seeing. In our app, we sometimes
push updated classes to a server. This does not work from the ikvmc DLL. I
had thought it might be another pathing issue, but it sounds more like what
you're mentioning here.
InputStream inStream = classLoader.getResourceAsStream(path);
Am I correct in understanding that we'll need to use a more generic file
stream, instead, to load the classes under IKVM?
Thanks,
Paul

Post by Volker Berlin
It look like that your framework try to access the stream of
com.datastax.driver.core.Cluster$Builder.class. Because class resources
are not available IKVM that it try to generate a stub of the stream which
is failing. If this is the case then it look like a bug in IKVM.
Which version of IKVM do you use?
Volker
Hi folks,
I am looking for help on using IKVM with the spring framework. We are
using the ‘one large DLL’ solution to compile a large number of our
libraries. We recently added the spring framework to these.
Compiling everything together with ikvmc works but on initialization of
the spring framework, the ikvm class loader behaves differently than the
class loader of the standard JVM. The class loader of the standard JVM
tolerates that some extensions of the spring framework are missing, whereas

[Volker Berlin]

Hi Paul,

Do you have a .NET client which contains Java class resources on the
classpath?

The problem is that the IKVM compiler will remove all class files. The
compiler can not detect that you want not execute this classes and want
send it to a server. My suggestion is to pack the classes for the server
in a zip file and add this zip file to your jar. Or simple rename the
extension of the class file. Then the IKVM compiler will handle it as
resources.

On the way to send executable code from the client to the server is a
very bad practice. This sounds like a very large security hole.

Volker
