IEC 1508 recommends the use of a safe subset of Ada
for SIL4 components. SPARK is probably the language of choice
for the design of such systems.
C is only allowed for SIL1 and SIL2 components, C++ is not at all
recommended for any safety critical software.

Don't know about Java, but the JavaSoft License conditions
prohibited the use of Java in any safety critical applications
the last time I saw them.
