Hi Ceki,
Can you read JEP 223 <http://openjdk.java.net/jeps/223> it describes how
the new version string is implemented in JDK 9.
Is logback working with JDK 9 ?

Hi All,
We started testing SLF4J and logback projects using Java 9, more
specifically build 154. As such, I would appreciate if you could add
the following details onto the Quality Outreach wiki page.

Initial testing results
=======================
Initial testing indicates that log4j version 1.2.x is unable to parse
the result of the call System.getProperties("java.version"). The
returned string is "9-ea". However, log4j 1.2.x expects a string in
the form "1\.*", for example "1.6", "1.7" etc.
If the string is not in the correct form, log4j 1.2.x conservatively
assumes that it is running under Java 1.1 and disables certain
important functions, such as MDC support. The code in question is the
static initializer of the org.apache.log4j.helpers.Loader class.
Log4j 1.2.x is no longer maintained. However, there are innumerably
many projects which still use log4j 1.2.x.
I would suggest that the string returned be in the form "1\.9*" such as
"1.9EA" so as not to break log4j 1.2.x under Java 9.
Many thanks in advance for taking the above into consideration.
Best regards,
