Hello everyone,

Very much a newbie question, but I'm looking to see if anyone has any luck with configuring settings within Java's control panel. The process of upgrading Java, I've found, is by simply dropping the .pkg into CA. However, does anyone have a best suggestion for configuring settings:

Specifically disabling - Use SSL 2.0 compatible ClientHello Format
- Use TLS 1.1
- Use TLS 1.2

Thanks!

Those settings appear to be saved in /Users/yourname/Library/Application Support/Oracle/Java/Deployment/deployment.properties.

My favorite way to track down what file is modified is to use a tool called 'fs_usage'.

  1. type 'sudo fs_usage > /tmp/fsuse.out'
  2. Make your edit (in this case to java prefs.
  3. Press Control-C to end the fs_usage task
  4. Look through the output (type: 'more /tmp/fsuse.out') for any preference file that might contain your data. Note that fs_usage generates a lot of output, so get your java control panel ready before you start it.
