Jones, Richard and King, Andy (2005) A Fast Analysis for Thread-Local Garbage Collection with Dynamic Class Loading. In: Fifth IEEE International Workshop on Source Code Analysis and Manipulation.
Long-running, heavily multi-threaded, Java server applications make stringent demands of garbage collector (GC) performance. Synchronisation of all application threads before garbage collection is a significant bottleneck for JVMs that use native threads. We present a new static analysis and a novel GC framework designed to address this issue by allowing independent collection of thread-local heaps. In contrast to previous work, our solution safely classifies objects even in the presence of dynamic class loading, requires neither write-barriers that may do unbounded work, nor synchronisation, nor locks during thread-local collections; our analysis is sufficiently fast to permit its integration into a high-performance, production-quality virtual machine. This paper is a shorter version of our http://www.cs.kent.ac.uk/pubs/2004/1970/.
