[native-image] UnsupportedFeatureError: ObjectOutputStream.writeObject()

[cushon]

I ran into this stack trace using native-image on an application that uses Java serialization:

com.oracle.svm.core.jdk.UnsupportedFeatureError: ObjectOutputStream.writeObject()
	at java.lang.Throwable.<init>(Throwable.java:265)
	at java.lang.Error.<init>(Error.java:70)
	at com.oracle.svm.core.jdk.UnsupportedFeatureError.<init>(UnsupportedFeatureError.java:29)
	at com.oracle.svm.core.jdk.Target_com_oracle_svm_core_util_VMError.unsupportedFeature(VMErrorSubstitutions.java:98)
	at com.oracle.svm.core.jdk.Target_java_io_ObjectOutputStream.writeObject(JavaIOSubstitutions.java:67)

I didn't see a discussion of serialization in LIMITATIONS.md. Is this something you plan to support and haven't gotten to yet, or is serialization not supported?

[cstancu]

It is not currently supported because we haven't gotten around to do it yet.

Does 'closed' mean this issue has been rejected, or is it still on the todo list? The use case I have is that I have to send exceptions or user-defined data types across the wire, and these need to be serialized.
I can handle primitive or well-defined data types (e.g. java.lang.Integer), but fall back to Java serialization for the above mentioned types.

I encountered a similar issue when using the following method of java.security.KeyStore class

public final void load(InputStream stream, char[] password)
        throws IOException, NoSuchAlgorithmException, CertificateException

and this is the stack trace

Same error with some Google App Engine apps.... If only time would block the fix, I recommend reopening this bug...

[razem-io]

Guys, he only closed another issue which was a duplicate (#519) and referenced it. It had a similar name, which might have caused the confusion. This issue (#416) is still open.

We also have the problem with Gradle: the daemon may send messages to the client in serialized form (in particular exceptions). When the client gets the message, it fails with:

I'm also facing the same problem trying to use apache httpclient:

And again on a different project.

I also get this error, when trying to invoke Oracle DB with ojdbc7.

Can Graal work with ojdbc7 (v 12.1.0.2)?

[ziyilin]

Any updates on this issue? Seems still not supported in 19.2.
What's the root cause of this issue?

@cstancu GraalVM 19.2.0 have the same problem, can we have any workaround?
