In the Utilities menu in vergil, PDFAttribute triggers an exception under Java 1.8. Edward saw this exception under Mac OS 10.9, Christopher has not seen it under 10.7

However, running "cd $PTII/doc/test/junit; make" causes problems under Mac OS X and Linux.

Force everything to get expanded ptolemy/configs/full/configuration.xml

If you get a 'X connection to xxx:11.0 broken' message, then

We are running PDF-renderer from https://java.net/projects/pdf-renderer. That tree has not been modified recently.

Line 222 of PDFColorSpace.java is marked below:

/**
* get the PDFPaint representing the color described by the
* given color components
* @param components the color components corresponding to the given
* colorspace
* @return a PDFPaint object representing the closest Color to the
* given components.
*/
public PDFPaint getPaint(float[] components) {
---> float[] rgb = cs.toRGB(components);

return PDFPaint.getColorPaint(new Color(rgb[0], rgb[1], rgb[2]));

https://bugs.openjdk.java.net/browse/JDK-8032243?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab - a bug in OpenJDK that describes the issue.
https://github.com/katjas/PDFrenderer is more active, though it says "some colours are displayed incorrect, there seem to be open issues regarding colour space handling"

https://issues.apache.org/jira/browse/PDFBOX-2454 leads to https://issues.apache.org/jira/browse/PDFBOX-2184, which says:

"I have a new theory, this could be a race condition in Java's CMM code caused by lazy initialisation, which would explain why we don't get an error until toRGB is called. The Open JDK code for ICC_ColorSpace.java clearly uses lazy initialisation of the color transform object:"

159 public float[] toRGB (float[] colorvalue) {
160
161 if (this2srgb == null) {
162 ColorTransform[] transformList = new ColorTransform [2];
163 ICC_ColorSpace srgbCS =
164 (ICC_ColorSpace) ColorSpace.getInstance (CS_sRGB);
165 PCMM mdl = CMSManager.getModule();
166 transformList[0] = mdl.createTransform(
167 thisProfile, ColorTransform.Any, ColorTransform.In);
168 transformList[1] = mdl.createTransform(
169 srgbCS.getProfile(), ColorTransform.Any, ColorTransform.Out);
170 this2srgb = mdl.createTransform(transformList);
171 if (needScaleInit) {
172 setComponentScaling();
173 }
174 }
175 ...

"I've added a call to toRGB in the constructor of PDDeviceCMYK() which is called statically and so will be thread safe. Hopefully this will prevent the race condition because it will cause "this2srgb" to be initialised."

Add a hook on JVM start. In the hook, just put :

Class.forName("javax.imageio.ImageIO");

This will force the class loader to load the class and do whatever static initialization it needs. I think your problem is the class is being loaded on a thread, and the 2nd thread is trying to use ImageIO, which cause a clash on locks (or lackof locks) obtained on color profiles.

Edit: You can add this line to your main too. Make sure it's the first line you call. ImageIO was not the class responsible for ColorSpace initialization.

Class.forName("java.awt.color.ICC_ColorSpace");
Class.forName("sun.java2d.cmm.lcms.LCMS");
does the trick
