<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">As far as the second point is concerned, yes, I am aware you can specify the required JRE version (or versions) inside the JNLP launcher for a Java Web Start application. But the reason why I asked the question is that I was especially afraid that minor Java releases could break the compatibility with VTK. If this was the case, then being able to specify the JRE version wouldn't be enough to deliver an acceptable user experience. In fact, suppose that I build and link VTK agains Java v7u21 and I ship my VTK-based Java Web Start application. Then, after a while Java 7u22 comes out: if this broke the compatibility with VTK, I could require Java v7u21 to my users, but where would they find it, when it has become an old version?</div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">In any case, if only major Java releases may break this compatibility, this should not be a big issue. </div>
<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">On the other side, issue 1. (if present) is quite critical in my opinion, and difficult to workaround. It may be a show-stopper for Java+VTK under Mac, and this would be a real pity!</div>

<p dir="ltr">Hi all.<br>
I have a couple of questions in this regard:</p>
<p dir="ltr">1 - Will VTK 6 work with Java 7 on Mac OS X? According to my experience, Oracle's JVM (v7) works much better than Apple's one (v6), especially for web deployments (Java Web Start / Java Applet).</p>
<p dir="ltr">2 - How "sensitive" is VTK to the version of the JRE it is linked against vs the version the application is run with? It must absolutely be the SAME EXACT version? Or there is some "tolerance"? The crucial point is the version of the jawt library? Or what else? I ask this question because especially with web deployments (e.g., Java Web Start) it is very difficult to control which exact JRE version the client is running.</p>
<p dir="ltr">Thanks in advance for your comments.</p>
<p dir="ltr">Regards,</p>

<div dir="ltr">Hi VTK fans,<div><br></div><div><div>After prototyping some cool prototype visualizations with the help of ParaView I'm attempting to implement them in an existing Java-based engineering application. I have burned several couple days trying to get some combination of VTK and Java to play nicely together on MacOS X, running into issues ranging from detached rendering windows to core dumps when trying to use vtkXMLUnstructuredGridReader. </div>
<div><br></div><div>Since I have my client excited about using VTK after seeing the ParaView results, I'm anxious to make a final determination as to whether we can reliably make use of VTK in our engineering app or if I need to look for other options. :-( I'm interesting in hearing from other's who've successfully deployed Java-based VTK apps on MacOS X.</div>
<div><br></div><div>I've attempted to use Java 6 and 7 (our app requires 7), as well as VTK version 5.6, 5.8, 5.10.1, and the GitHub master. With Java 6, rendering windows appear where they should, but appear as separate window entities with Java 7. Putting that aside, all the combinations I've tried crash when attempting to use vtkXMLUnstructuredGridReader and render the result. I've tested with my own .vtu files as well as the VTKData5.10.1/Data/quadraticTetra01.vtu </div>

I've attempted attaching Xcode to the running process and had cases when it crashes in either vtkDataSet::GetBounds() or vtkXMLReaderJava::Java_vtk_vtkXMLReader_SetFileName_12() (the latter in the call to op->SetFileName()). Given the seeming benign nature of the crash sites, I suspect memory corruption has occurred before then.
