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 ( Versions < 3.7.9.17038 )
- 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
