Hallo,

i have a rcp application which uses Java7 features. In my IDE all works fine and i can use the java7 features. I have define and set the execution environment on JavaSE 1.7.
All works fine! But if i deploy my application, the code fragments which uses Java7 features dont work. I get the following Exception:

Quote:

For example (using String-Switch):
Cannot switch on a value of type String for source level below 1.7. Only convertible int values or enum constants are permitted.


My application uses the correct runtime (JRE7). I dont know where's the problem.
Can someone help me ...

THX

Maybe you did not use 1.7 to compile the source when doing the export.

Make sure you also specify the execution environment in the manifest file.
