[jira] [Commented] (PDFBOX-5479) PDFTextStripper needs 1GB heap for a 3.6 MB pdf
[ https://issues.apache.org/jira/browse/PDFBOX-5479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17797141#comment-17797141 ]

Different font objects that point to the same font file. So the font is opened each time and all tables are read and stored. And since 3.0 we read much more tables than in 2.0.
