Maven is using SLF4J for its logging. Its default binding is an extended simple logger flavor of SLF4J, which means it can be configured using simplelogger.properties file (in Maven conf/logging directory) or using system properties.

To add timestamps to log output we need two properties:

• org.slf4j.simplelogger.showDateTime: a boolean to add the timestamp in the output
• org.slf4j.Simplelogger.dateTimeFormat: a SimpleDateFormat which formats the timestamp activated by previous property

We can do it permamently in the simplelogger.properties file or add these system properties on the JVM, possibly using MAVEN_OPTS

-Dorg.slf4j.simpleLogger.showDateTime=true -Dorg.slf4j.simpleLogger.dateTimeFormat=HH:mm:ss,SSS

It's safe to use LF everywhere now

git config --global core.eol lf
git config --global core.autocrlf input

Make sure all local files are recreated with the correct line-endings

$ docker run --privileged --pid=host -it alpine:3.8 \
nsenter -t 1 -m -u -n -i sh

• --rm : removes the container after it is stopped
• -ti (or -t -i) : adds a tty and leaves the standard input opened
• --privileged : grants additional permissions to the container, it allows the container to gain access to the devices of the host (/dev)
• --pid=host : use the host's Process ID Namespace. Allows the container to use the process tree of the Docker host (the machine in which the Docker daemon is running)

JDBC client sends command to setup session when physical connection is established via a modified AUTH_ALTER_SESSION OCI attribute in the authentication phase.

If the JVM time zone is one of the magic constants in the oracle.sql.ZONEIDMAP class and oracle.jdbc.timezoneAsRegion = true (default) then AUTH_ALTER_SESSION looks like this (where Etc/UTC is the default timezone picked up by the JVM)

ALTER SESSION SET TIME_ZONE='Etc/UTC' NLS_LANGUAGE='POLISH' NLS_TERRITORY='POLAND' 

which can fail with
