Not that anyone ever believes Oracle employees when we say “it works for me”, but “it works for me”. I installed with 10.9.3 with 1.7.0_60 installed (and have subsequently upgraded to 10.9.4).
Sten, first, what does the log file say?
Following that, can you try 3 things from the command line:
1) Run “shasum ./jdev_suite_121300.jar” This should return the following checksum to prove the validity of your file: 5233616b752658c948230b1a8ed366205b36d807
2) Execute “jar -tvf ./jdev_suite_121300.jar” to see if it further validates from the jar utilities perspective.
3) Finally also try the following instead to install the jar:
/usr/libexec/java_home –version 1.7.0 –exec java -jar ./<filename>.jar
Let us know how you fly.
