[Laszlo-dev] Reentrant lock hell

[Benjamin Shine]

I have also seen that. I suspect it is caused by some joy in the WEB- 
INF/lps/server/src/build.xml, such as for instance it only compiles  
the oswego classes into class files but doesn't put them in the lps  
jar. It's interesting that it is a class-not-found error; perhaps we  
hardly ever even try to use the oswego classes except for when  
there's a cache problem.
