workaround for this issue.
You can create a file in the $BEAHOME/utils/bsu
directory of the target bea installation called “bsulaunch.properties” which can contain the following properties:
JVM_ARGS — Args passed to the java VM when invoking bsu.jar.
BSU_ARGS — Args passed to bsu when it’s invoked.
So, putting the following in the properties file should allow bsu.jar to use
JVM_ARGS=-Dhttp.proxyHost=host -Dhttp.proxyPort=8080 -Dhttp.proxySet=true
