> Upon analyzing the thread dump file using the Memory Analyzer Tool (MAT), it was observed that the class `org.apache.fop.layoutmgr.inline.LineLayoutManager$Paragraph` was occupying the largest portion of heap memory. Specifically, this class used approximately 1.5 GB per thread, with around 20 such threads present in the system.
> As this component is managed by the Apache™ FOP Project, we would require to raise this with you on priority.
