I'm using PDFbox to render a PDF with forms in a java applet and when I change the forms information for the first time, it takes way too much time to reflect the new information in the displayed form and PDFBox logs the following two messages:
[date] org.apache.pdfbox.util.PDFStreamEngine processOperator
INFO: unsupported/disabled operation: BMC
[date] org.apache.pdfbox.util.PDFStreamEngine processOperator
INFO: unsupported/disabled operation: EMC
Consequent form changes are reflected in an accepted time frame and PDF don't log that information anymore.
Questions:
- Is the first time slowness directly related to the logged information or is it to be expected?
- If it's not to be expected, how can one solve this problem?
