[Building Sakai] for edia scorm player and sakai 2.7

[Roland Groen]

Hi Steve,

Thank you for pointing this out. Please take a look at:

https://source.sakaiproject.org/contrib/edia/scorm/branches/2.7.x/scorm-impl/service/src/java/org/sakaiproject/scorm/service/sakai/impl/ContentPackageSakaiResource.java

and notice that it does not matter what
org.sakaiproject.content.api.ContentResource.getContentLength()
returns. In case of an int it will implicitly cast to long, and in case of
al long it will work anyway. Portable code, right ;). No need to change code
for 2.7 regarding this issue.

The binary code, on the other hand, will be different once compiled. This
NoSuchMethodError can only happen if it is compiled agains long, and
executed agains int. Or the other way around, of course.

So: this issue can ONLY happen if the compilation libraries are different
than the runtime libraries. My recommendations still stand.

With kind regards,
