Why JBoss does not allow to use multiple endorsed directories?

The system property java.endorsed.dirs specifies one or more directories that the Java runtime environment will search for such JAR files.

Why does JBoss allow to use only one endorsed directory?

There is following code in jboss-5.1.0.GA\bin\run.bat:

set JBOSS_ENDORSED_DIRS=%JBOSS_HOME%\lib\endorsed
"%JAVA%" %JAVA_OPTS% ^
   -Djava.endorsed.dirs="%JBOSS_ENDORSED_DIRS%" ^
   -classpath "%JBOSS_CLASSPATH%" ^
   org.jboss.Main %*

I nee开发者_开发知识库d to put one jar to endorsed directory.

But I cannot put it to %JBOSS_HOME%\lib\endorsed directory because on production environments this directory is readonly.

But I can change startup parameters of JBoss.

So I decided to add one more endorsed directory via startup parameters.

But I cannot do it because JBoss uses only its own java.endorsed.dirs="%JBOSS_ENDORSED_DIRS%".
