Have you set the 'language level project' to "5.0"? (In the 'module
settings dialog')?

Or more correctly please ensure the JDK configured for the project is 1.5

yes, language level for project is 5.0!
but, this is a module of a project, another module is j2me game, so it can not set to 5.0, just 1.4, I guess the problem is here

yes, the language level is 5.0 and the jdk is java 1.5
this is a module of a project, another module is j2me game with language level 1.4 and wtk 2.2
so I guess the IDEA do not know the module is of 5.0 and antoher module is of 1.4
this is a bug? I believe you can reproduce it easy:
new a j2me project
addd a java module, set language level to 5.0 and jdk to 1.5
write 'System.out.printf("hello, IDEA") '
watch what happens?

Unfortunately this is a known issue with IDEA and mixing
modules with different language levels can result in a lot
of pain and frustration.
