hmm looks like I didn't realize my ide had navigated me to another class getByteBuffer is
on MemClassLoader... Ah I see no I confused the method name when I wrote the comment I meant
to say getFileContent (on JarContent, or it's equivalent) couldn't return a ByteBuffer

> In some cases search components or analysis classes may utilize a large dictionary or
other in-memory structure. When multiple cores are loaded with identical configurations utilizing
this large in memory structure, each core holds it's own copy in memory. This has been noted
in the past and a specific case reported in SOLR-3443. This patch provides a generalized capability,
and if accepted, this capability will then be used to fix SOLR-3443.
