Yes, and it explains why in the earlier thread "Re: unconfined_execmem_t 
for /usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/bin/java ?" we had 
/usr/lib/jvm/java-1.5.0-sun-1.5.0.06/jre/bin/java labelled as bin_t 
rather than java_exec_t with the following file context entries in the 
base policy:

/usr/lib(.*/)?bin/java([^/]*)?     regular file 
system_u:object_r:java_exec_t:s0
/usr/lib/jvm/java.*/bin/.*         all files 
system_u:object_r:bin_t:s0
