Description
Restore possibility to create a release with Java9+
The explanation for this is given in apache/felix#114 :
Java 9 introduces overridden methods with covariant return types for the following methods in java.nio.ByteBuffer:
position (int newPosition)
limit (int newLimit)
flip ()
clear ()
mark ()
reset ()
rewind ()
In Java 9 they all now return ByteBuffer, whereas the methods they override return Buffer,
resulting in exceptions like this when executing on Java 8 and lower:
java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer
This is because the generated byte code includes the static return type of the method, which is not found on Java 8 and lower because the overloaded methods with covariant return types don't exist (the issue appears even with source and target 8 or lower in compilation parameters).
The solution is to cast ByteBuffer instances to Buffer before calling the method.
