> NDEBUG is a standard macro for C/C++ programs used in function assert(). It's recommended to define it for release build to remove assertion. Some programs use this macro also to remove other debug/trace code in release mode.
> JDWP agent from jdktools/jpda component includes a lot of trace messages, which facilitate debugging and bug fixing. These trace messages gather a lot of additional data and significantly slow down agent performance and may cause leaks of memory and JNI references uses for additional data. Trace message should be removed from release build of JDWP agent by defining standard macro NDEBUG. Since jdktools component uses build scripts from classlib, then classlib build should define NDEBUG for compilation of native sources in release mode.
