Error message after update to 4.10

Hello

I installed the Flex 4.10, but I keep having a message error, I
not sure if this error is related with my project or the compiler. But
just happen when I select Flex 4.10, If I use Flex 4.9 it works.

Im using Eclipse Juno+Flex 4.10+Blazeds

Thanks a lot

The error message from Eclipse is this
