[jira] [Comment Edited] (PDFBOX-4836) Reduce the usage of
ScatchFileBuffer when parsing a pdf
[ https://issues.apache.org/jira/browse/PDFBOX-4836?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17198807#comment-17198807 ]

-------------------------------------------------------------------
RandomAccessReadBuffer(InputStream) creates an empty buffer if the InputStream is from an URL.openStream() because available() returns 0. I have this on jdk8.
I noticed this in the recently committed code at the end of the TestPublicKeyEncryption class, it doesn't work when loadPDF(url.openStream()) is called.
