[jira] [Comment Edited] (PDFBOX-4450) java.lang.OutOfMemoryError
when validating pdf
[ https://issues.apache.org/jira/browse/PDFBOX-4450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16757698#comment-16757698 ]

pages 136 has a loop:
{code:java}
Root/Pages/Kids/[135]/Resources/XObject/Fm0/Resources/XObject/R1579/Resources/XObject/R1579/Resources/XObject/R1579{code}
There is no simple solution for this… For your file, the problem will likely go away by using
{code:java}
document.getContext().getConfig().setMaxErrors(100){code}
Because the first few pages will produce enough errors.
I also tried with VeraPDF, but that one aborted with an NPE, see linked issue.
