Steps to reproduce the issue
Drop "Tika-Issue-Full-CPU.PDF" file (attached to the issue) into any folder.
When SOLR tries to index the content, CPU consumption will be maintained nearly 100% for a long time. Alfresco stops to work after a while due to this CPU consumption.
The thread dump shows how Tika is trying to extract content from the PDF:
