some further prodding revealed that the xattr name size as calculated by XAttrSizeSetter is not exactly the size of the name under some circumstances which means that the buffer is to big and random memory locations are read after the last nil terminator.

I have fixed this issue on my fork as well and could make another pull request if you like but it really is a one-line change:

Filesystem3ToFuseFSAdapter.java:470

replace: size+= (int) ((float)xattrName * enc......
with : size += xattrName.getBytes("UTF-8").length+1

.getBytes() can throw an exception so surround with try catch.

cheers,
