PDFStreamEngine swallows errors when jbig2-imageio is not installed

[Eduardo Quintanilla <eq...@bnext.mx>]

Hello,

I would like to know if the Apache PDFBox JBIG2 plugin is loaded to solve a weird bug where the plugin is not present and the JAR jbig2-imageio is definitely added in the classpath.(Sometimes it works).
After executing ImageIO.scanForPlugins()  the issue is solved. Any recommendations of the best way of determining if the plugin is loaded? Maybe a class to be checked that is loaded in the classpath, Is that a good idea?
Related issue: https://issues.apache.org/jira/browse/PDFBOX-3760

Best regards,
Eduardo Guadalupe Quintanilla Flores

Hi,

Call ImageIO.getImageReadersByFormatName() and see what result you get.
