I personally do not use this, but some java software (like Zend) packed
with InstallAnywhere does. 
The InstallAnywhere provides installation and launcher scripts. The
script uses LD_ASSUME_KERNEL for some cases, thus it fails to launch
programs e.g java.

It seems that it's an installer issue, or is there a way to "turn on"
LinuxThreads support in FC5 ?
