To pass run arguments to the JVM software, set the jvm_invocation environment variable to start the JVM software with those arguments, as in the following example.
jvm_invocation="java -Xdebug -Xms512 -Xmx1024 -Xcheck:jni"
This example causes dbx to start the JVM software as follows:
java –agentlib:dbx_agent=sync= -Xms512 -Xmx1024 -Xcheck:jni
