The trick of writing generic types into class files of versions < 49
does no longer work with javac from OpenJDK 7:
/comphelper/qa/complex/comphelper/Map.java:154: error: type Pair does
not take parameters
Pair< ?, ? >[] initialMappings = new Pair< ?, ? >[ _keys.length ];
There appears to be a related JDK bug for this, at some time javac had
an undocumented option to produce similar class files that are also
rejected now, this has been closed as "Not a Defect":
