Jukka Zitting commented on PDFBOX-511:
--------------------------------------
I committed the patch in revision 814536.
While reviewing the code I found out that new java.awt.Color instances are
getting created whenever a new drawing operation is performed. With some
refactoring it should be possible to reduce the number of new Color instances
to only the number times the color actually changes due to SetStroking- or
SetNonStrokingColor operations. Since the above-mentioned JVM crash is
non-deterministic and especially since it seems to be related to
garbage-collection, reducing the number of createColor() calls and short-lived
color space instances should notably reduce the likelihood of these crashes.

> Key: PDFBOX-511
> URL: https://issues.apache.org/jira/browse/PDFBOX-511
> Project: PDFBox
> Issue Type: Bug
> Components: PDModel
> Affects Versions: 0.7.3
> Environment: Java HotSpot(TM) Client VM (11.3-b02 mixed mode
> windows-x86), Windows XP Build 2600 Service Pack 3
> Reporter: Jukka Zitting
> Priority: Critical
> Attachments: PDFBOX-511.patch, PDFBOX-511.patch

> Similar to PDFBOX-488, the JVM (here JDK 1.6 on Windows XP) crashes when
> PDFBox tries to create a java.awt.Color instance with some specific ICC
> profile. The root cause of the problem is a low-level bug in the JVM (most
> likely http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6645513), but it
> would be really good if PDFBox could work around that issue or at least throw
> a normal exception in troublesome cases instead of crashing the entire JVM.
> See below for the relevant parts of the crash report.
