FATAL ERROR in native method: processing of -javaagent failed

Cause

The Contrast Java agent requires a small amount of space to use as a working directories. During startup:

• The Java agent will extract a few jar files to the java tmp directory
• The Java agent will create/write files to it's working directory

Resolution

To avoid these type of exceptions, pre-create these folders and set permissions so the application server has full access to them.  These directories can be controlled with the following JVM properties.

• -Dcontrast.dir=/path to folder/       Location of Contrast "workspace"
• -Djava.io.tmpdir=/path to folder/    Location of java tmp directory
