Basically Oracle Java 7 and 8 changed their API with the Cocoa code which break the old rendering technique used for Java.</div>
<div>To overcome that issue we provide a vtkJoglPanel / vtkJoglCanvas where VTK handle the OpenGL code and we let the JOGL code do the graphical integration.</div><div><br></div><div>To enable them, you will need to get JOGL and build VTK with it with additional options and paths.</div>
<div>But we are in the process of providing binaries of VTK for each platform in an automatic manner. Unfortunately that process is not complete yet, but you can download those binaries from the web by going to the VTK dashboard (<a href="http://open.cdash.org/index.php?project=VTK" target="_blank">http://open.cdash.org/index.php?project=VTK</a>) and downloading the generated files by clicking on the yellow box.</div>
<div><br></div><div>Also another known issue is that altair.kitware does not properly compile the Java files, which means that it's generic vtk-6.0.1.jar does not contains any class files.</div><div>But you can get that same file from any other platform.</div>

Less so on Mac however, mostly due to Apple’s custom JVM implementation (1.6) messing with the lightweight/heavyweight thingy, and the dramatic changes when switching to Java 1.8 (Oracle). </div>
<div><br></div><div>— The story starts when compiling VTK with Java bindings (after I installed Oracle’s JDK 8 on Mavericks 10.9.2, Xcode 5.1). At runtime, vtk viewers that used to work under JDK 6 suddenly cause a bad crash (note that this also happened with Oracle’s JDK 7):</div>

</div><div><br></div><div>— I figured VTK probably wasn’t properly talking to JDK 8, and noticed in CMakeLists that the JAVA_XXX flags were pointing to some weird bits of Java frameworks inside Xcode (in a MacOS10.9 resource bundle), therefore I changed them to:</div>
