[jira] [Commented] (PDFBOX-3267) Using threads results in different images

["Tilman Hausherr (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-3267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15191114#comment-15191114 ] 

Tilman Hausherr commented on PDFBOX-3267:
-----------------------------------------

It worked fine for me a few times. Then I got a concurrent something exception in {{ICC_Profile.getInstance}} in PDICCBase.java. As a quick solution, I enclosed this in {{synchronized(LOG)}} and it stopped. But I never got a "Not equals".

It would be interesting if you'd save the different images and post them here.

Your polling condition should have an "or" instead of an "and" IMHO. (I got an NPE once)
