This is a multi-threading problem with LCMS version 2.5. It was claimed to have
been fixed with LCMS v2.6, but many OS are still running the older packages. I
have code that parses PDF files. It is running in a production environment on
random PDF files and with lots of threads. I was able to stop the error (~2
years ago) by adding "syncronized" keyword around the following block of java
code:
ICC_Profile profile = ICC_Profile.getInstance(byte[]);
ICC_ColorSpace colorSpace = new ICC_ColorSpace(profile);
int numComponents = 3; // From PDF dictionary, typically '3' (RGB).
float[] components = new float[numComponents];
// Test that ICC_Profile can be parsed
// Generates an exception on malformed byte[]
// Crashes JVM sporadically if not forced inline by 'syncronized'
new java.awt.Color(colorSpace,components,1f);
If it helps, here's my java method (won't compile as it is missing methods):
public static synchronized PDFColorSpace getICCColorSpace(PDFToken
dict) throws IOException {
PDFColorSpace cs=null;
PDFToken nToken = dict.getDictionaryItem(N);
int numComponents = (nToken==null) ? 1 : nToken.getInteger();
try {
ICC_Profile profile =
ICC_Profile.getInstance(dict.getStream().toString8().getBytes());
// This does not prevent JVM Crash with BELL.SW
// if (profile.getNumComponents() == numComponents) ...
ICC_ColorSpace colorSpace = new ICC_ColorSpace(profile);
cs = new NativeColorSpace(TypeICC,colorSpace);
// Test if ICC_Profile is OK. Will throw Exception (or
even crash the JVM)
// eg: Cik#99001898,
http://www.siemens.com/investor/pool/de/investor_relations/events/hauptversammlung/2012/dividendenbekanntmachung.pdf,
pg0
// eg: JVM Crash, Cik#99002137, BELL.SW
float[] components = new float[numComponents];
new java.awt.Color(colorSpace,components,1f);
} catch (Exception e) {
cs=null;
}
return cs;
}

~~~ PS
When I tried to compile BugIIO.java on openjdk-6 and run it on openjdk-6, the
program finishes normally (no crash).
To clarify:
1. This bug affect OpenJDK 7 (7~b147-2.0-0ubuntu0.11.10.1) (tested on
oneiric).
2. This bug does *not* affect OpenJDK 6 (6b23~pre11-0ubuntu1.11.10) (tested
on oneiric).
