Jackrabbit oak: Unable to remove tar file ( java.nio.file.FileSystemException )

[rajesh]

Hi ,

I am using Jackrabbit oak ( 1.8.2 ). I am running fileStore.fullGC() method
for garbage collection in local repository. But it throws following error
from the log.

2018-04-03 16:51:29.876 DEBUG 10448 --- [rMK flush [oak]]

If I set the System.setProperty("sun.arch.data.model", "32"); It works fine.

Should I set this by default ?  Will this cause any problem in the
application because of setting this prop ?

Thanks.
