Integration

In Sun Web Server 6.1, I'm finding a memory leak when using servlet filters. I've even created a "no op" servlet filter. When it's registered, every 10000 hits or so to filtered static content will eat up about 5 to 10 MB of RAM. The JVM heap size doesn't increase.

When I remove the filter, I've hit the same static page on the server 50000 times without seeing an increase in memory usage by the process.

This is on Windows 2000, and I think the Sun Web Server 6.1 is SP1. I haven't tried SP2 yet.

For reference, here's the filter I put in:

public class NoOpFilter implements Filter
{
public void init(FilterConfig arg0) throws ServletException {}

public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{
chain.doFilter(request, response);
}

public void destroy() {}
}
