We are preparing a log4j 1.2.16 release over at Logging Services and
adding OSBi bundle metadata was on our bug list (https://issues.apache.org/bugzilla/show_bug.cgi?id=432820
). I've taken a shot at modifying our pom.xml to use maven-felix-
plugin and would appreciate any comments.
Here is the situation:
log4j-1.2.16.jar contains classes in org.apache.log4j and child
packages. org.apache.log4j.lf5 and org.apache.log4j.chainsaw packages
are provided in the jar for compatibility with earlier jars, however
neither are intended for use (LF5 is dead and Chainsaw 2 is its own
deliverable now). Those classes are suppressed from exporting.
log4j sniffs for IBM Visual Age in some diagnostic code which resulted
in "com.ibm.uvm.tools" in the default imports. Also, Agent.java which
has no known users loads com.sun.jdmk.comm.HtmlAdapterServer by
reflection. Imports of both those packages are suppressed.
Between the JMX, JMS, SMTP and other appenders, log4j does import many
java.* and javax.* packages. Those packages aren't essential to the
functioning of log4j, just specific appenders.
The changes to the pom.xml were:
