[x3d-public] Fatal X3DJSAIL error using JDK 8u202. Will try to downloadlatestJava binary version.

[John Carlson]

Thanks for your patience!

https://github.com/carlsonsolutiondesign/x3dpsail

Is ready to test again.

You may install in python (not Anaconda) via command prompt:

$ pip3 install x3dpsail

If someone can find a workable solution for creating an Anaconda channel and package installation instructions that would be great.

I got it to work in Anaconda by putting the package in my PATH, and restarting Anaconda.

I also had to do

from x3dpsail import x3dpsail

at the top of the file in jupyter lab.

Attached is a sample notebook that has a bug in it.  Should I offer a bug bounty?

I’ve got it worked down to the following code:

from x3dpsail import x3dpsail

(x3dpsail.ProtoBody()
    .addChild(x3dpsail.Transform()
        .setIS(x3dpsail.IS())
    )
)

The thing is, TransformObject extends X3DNode, so I am puzzled!

Traceback (most recent call last):
  File "passed.py", line 5, in <module>
    .setIS(x3dpsail.IS())
  File "jnius\jnius_export_class.pxi", line 760, in jnius.JavaMethod.__call__
  File "jnius\jnius_conversion.pxi", line 78, in jnius.populate_args
  File "jnius\jnius_utils.pxi", line 205, in jnius.check_assignable_from
jnius.JavaException: Invalid instance of 'org/web3d/x3d/jsail/X3DConcreteNode' passed for a 'org/web3d/x3d/sai/Core/X3DNode'

So it’s a java bug. See errors in below message.


Thanks,

John

“Works” with OpenJDK 12.0.1 binary—no JNI error. Please upgrade.

Here’s the error generated.

===========================================================================================================
But work on my abox.future.py bug below, pretty please?  With or without wrappers, it doesn’t matter which to me.

Here is the minimal code which fails.

import x3dpsail

(x3dpsail.ProtoBody()
    .addChild(x3dpsail.Transform()
        .setIS(x3dpsail.ISObject())
    )
)

addChild takes an X3DNode.
setIS returns a  TransformObject—an X3DConcreteNode

Please add to ProtoBodyObject.java an

addChild(TransformObject)

and/or

addChild(X3DConcreteNode)

You can do it at the same time you are adding addShaders() – see below.

Alternatively, you can make X3DConcreteNode inherit from X3DNode, I guess.   This seems best.  I’m not sure why it doesn’t already? How about TransformObject extend from X3DNode in the short term?   That’s not in the standard, right?  It looks like it already does.


This appears to be a Java issue.  What does the same Java do? AHA!

Previous versions of the jar work:

Warning: toFileStylesheetConversion(X3dToJson.xslt) is overwriting prior file ../data/abox.new.json

Time to back some changes out? Report bug to Oracle?

$ java -version
java version "1.8.0_202"
Java(TM) SE Runtime Environment (build 1.8.0_202-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.202-b08, mixed mode)
Thanks,

I don’t have the current version of Java on my system.  I don’t want to install the lastest JDK 8 under the new Oracle agreement.

HELP!

Please try on your own systems.
