If you attempt to install JDeveloper on OS X Mavericks or OS X Yosemite, you may run into a few common issues.

KDevelop showing the uses of a function in the bottom code browser widget. KDevelop showing the details of a problem in source code in the code navigation widget (just need to hover over the underlined text). Jdeveloper MAC OSx 10.9. All of a sudden Jdeveloper is running extremely slow. Typing is almost impossible as I have to stop a few sec after typing a character! The 'Close application' from menu takes about 15/20 minutes to complete. However deployment to Simulator time had not increased that much.

  1. The installer window is really small, and the only visible button is Exit.
  2. The installer may fail with an error indicating, 'Fatal error during installation...' The installer then terminates and cleans up the installation files. This issue occurs because the JDeveloper installer will not run with JDK7.
  3. You may get JDeveloper installed with Java for Mac 1.8; however, I have found that the Property Inspector crashes in a reproducible fashion which basically renders JDeveloper useless.
