  I experienced that the compilation goes without any problems on Uniprocess kernel, but that it halts on the way showing several javac/java pausing - linux-sun-jdk1.5.0 on SMP kernel which did not disappear with kill pid. (ps -alx|grep java result shown below).

  Successfully compiled uniprocess jdk1.5.0 does not run on multiprocess kernel though it runs fine on uniprocess kernel. 

  These java related compilation issues makes me suspect some racing condition on SMP, but it is seemingly only with java related.  Others work fine on SMP.
