To decompress entire PDF you may use

java -Xmx192m -cp Multivalent20060102.jar tool.pdf.Uncompress -exact file.pdf

If a particular page is needed to be decoded:

[language=java:16hhkgtu]PD4Document doc1 = new PD4Document(new URL(“file.pdf”), password);
String content = doc1.getPageContent(1);[/language:16hhkgtu]

For the time being it is not possible to disable JDK/OS diag output. But we could add the switch in the next versions.
