URLResourceReader caches jars in memory

[Brad Wood]

This is a long shot, but does anyone know why this class

https://github.com/markmandel/JavaLoader/blob/develop/java/networkClassLoader/src/com/compoundtheory/classloader/URLResourceReader.java

caches the entire binary contents of jars in memory?  I'm not talking about loading the classes, just reading the jar off disk and putting it in a byte array in memory.

I noticed it when analyzing some heap dumps of a Java process and I saw Javaloader was consuming a chunk of RAM due to this.  I'm just trying to figure out if there's a specific purpose for this since I assume the jar only needs read once when its classloaded so I'm not sure what the point of keeping the binary in heap is.  There is a "cache" parameter I can pass in, but it always gets set to true for individual files with no way to override.

Thanks!
