Hi Charles,

I think this could be possible.
The use of https://docs.oracle.com/javase/8/docs/api/java/nio/channels/FileChannel.html is made for multi-threaded environments accessing files.

Hi,

Could it be possible with Apache Karaf 2.4 that, when we have a huge number
of threads accessing JAAS Properties login Module, some thread could be
blocked/locked as we reopen every time the users.properties file (
http://grepcode.com/file/repo1.maven.org/maven2/org.apache.karaf.jaas/org.apache.karaf.jaas.modules/2.3.4/org/apache/karaf/jaas/modules/properties/PropertiesLoginModule.java?av=f#60)
?
