> Lucene/Solr runs its whole testsuite also with Java 9 EA releases to trigger
> bugs early. In our tests (Solr + TIKA) we found out that
> org.apache.pdfbox.util.PDFTextStripper throws a NumberFormatException in its
> static initializer when parsing the "java.version" system property. The
> reason for failure is a change in Java 9, where version numbers got a new
> format.
> There are 3 problems:
> - It should not assume that all components are really a number. So it should
> try/catch NumberFormatException and assign some "unknown" version
> - The code should really use "java.specification.version". This is
> standardized and only contains digits.
> - The code should also be prepared to handle version numbers without minor
> version! E.g. Java 9 only has "9" instead of "1.9" as its main version number.
> For the use case I would nuke this check and find a better workaround.
> Relying on String parsing for non-standardized system properties in a static
> class initializer is the reason why this bug is raised to level "Critical".
