Release version has Java strictness incompatibility

I just downloaded and installed zorba and zorba_modules from https://launchpad.net/zorba/+download

Cmake completed without issues on my system (unlike the bzr version which has a uuid.h detect bug as previously reported).

However, when running make, there is a java compile-time error in the ZorbaReadPdfModule class, which I guess may be to do with the default strictness of the particular javac available on my system, but seems a pretty fundamental Generics error.

Scanning dependencies of target zorba_read-pdf_module.jar.classes
org/zorbaxquery/modules/readPdf/ZorbaReadPdfModule.java:379: error: incompatible types: Map<String,COSObjectable> cannot be converted to Map<String,Object>
                        Map<String,Object> embeddedFileNames = embeddedFiles.getNames();
                                                                                     ^

The path to javac when I experienced this bug was as follows...

/usr/bin/javac -> /etc/alternatives/javac -> /usr/lib/jvm/java-8-oracle/bin/javac

By running

sudo update-alternatives --config javac

...I selected instead the compilers for java-7-oracle, java-6-oracle and java-7-openjdk-i386 as default bindings for javac but they generated the same fatal build error.

Did this ever build with a recent version of Java?
