Error while opening JDeveloper: Unable to create an instance of the Java Virtual Machine error

Some times we get an error message “Unable to create an instance of the Java Virtual Machine” while opening JDeveloper. We can resolve this problem by increasing the virtual memory space for Jdeveloper. Follow below steps:

  1. Find for file jdev.conf which is usually in the path <Jdev_Root_Folder>/ jdevbin/jdev/bin
  2. Search for a line with text “AddVMOption” and add this text “AddVMOption       -Xmx256M” below that line

After editing, the file should like below screenshot
