And, if "-Djava.library.path=$CPLEX_HOME" is needed for every BSP
tasks, you should use bsp.child.java.opts property. :-)
<property>
<name>bsp.child.java.opts</name>
<value>-Xmx2048m</value>
<description>Java opts for the groom server child processes.
The following symbol, if present, will be interpolated: @taskid@ is replaced
by current TaskID. Any other occurrences of '@' will go unchanged.
For example, to enable verbose gc logging to a file named for the taskid in
/tmp and to set the heap maximum to be a gigabyte, pass a 'value' of:
-Xmx1024m -verbose:gc -Xloggc:/tmp/@[email protected]
The configuration variable bsp.child.ulimit can be used to control the
maximum virtual memory of the child processes.

</property>
