java -jar jdevstudio11124install.jar
Today I tried it again and the installer does start but with a very small screen only showing the exit button:

| JDeveloper Installer with only Exit button |
As it turns out this is caused by a recent install of JDeveloper 12c on the same machine. That had forced me to install JDK version 7 which is now the default java runtime environment on my machine. Apparently the JDeveloper version 11 installer doesn't like java version 7, at least on Mac OS X.
The solution is rather simple. Run the following commands in a terminal window to start the JDeveloper 11 installer:
wMac:~ wilfred$ /usr/libexec/java_home -v 1.6 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home wMac:~ wilfred$ /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -version java version "1.6.0_51" Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509) Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode) wMac:~ wilfred$ /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -jar jdevstudio11124install.jar Extracting scripts to /var/folders/vl/qsk0dkgn39b2_4sdngwvcf840000gn/T/ Executing MacOS-specific pre-installation scripts You may be prompted to enter your Mac OS X password in order to create required directories and symbolic links Extracting 0%....................................................................................................100%
Line 1 runs java_home to get you the full path to the java version 6 home directory. Line 3 uses this path and adds "/bin/java -version" to run java from that directory to check its exact version. Make sure it is in fact a 1.6.0_xx version. Then finally line 7 uses java from that directory to run the installer. This time it just starts fine:
