Fix server crash when File-Based Debug Logger is enabled#602
Conversation
When the debug logger is enabled, LoggerConfigManager sets root JUL level to FINEST which makes Grizzly's DefaultFilterChain.executeFilter() check isLoggable(FINEST)=true and log the FilterChainContext object. In Grizzly 3.0.1, FilterChainContext.toString() has a bytecode bug where it does a checkcast to char[] on the message field. When the message is a LdapResponseMessage, the cast fails with ClassCastException that propagates through the RxJava pipeline causing a server crash. Fix: Limit org.glassfish.grizzly JUL logging to FINE level so that isLoggable(FINEST) returns false, preventing the broken code path. Also add toString() to LdapResponseMessage for better diagnostics.
