ABSTRACT
Our native Java compiler directly generates runtime structures in a persistent 
Distributed Shared Memory (DSM). The compiler has been used to build a general 
purpose PC Operating System (OS) on top of a persistent DSM memory. The persistent 
DSM operating environment lends itself naturally to an integration of symbol tables, 
class descriptors and naming during Java program compilation and execution. The linking 
and loading process is streamlined and the persistent storage property makes a traditional 
loader redundant.

After a brief overview of the Plurix OS we discuss traditional linking strategies 
and present extended linking perspectives in the persistent Plurix DSM. This includes 
a novel immediate linking scheme offering the flexibility of dynamic binding while 
detecting errors at linking time. The remaining task of class initialization is 
performed only once by the Plurix Java compiler. To deal with the semantics of 
distributed Java static class variables we propose extended initialization rules 
together with a more flexible type checking scheme.
