A signal handler function must be very careful, since processing elsewhere may be interrupted at some arbitrary point in the execution of the program. POSIX has the concept of “safe function”. If a signal interrupts the execution of an unsafe function, and handler either calls an unsafe funct...
size_t _byte_map_size; // in bytes jbyte* _byte_map; // the card marking array ... } 可以发现 cardTableModRefBS 通过枚举 SomePublicConstants 来定义对应的内存块 card_size 的大小即:512KB,而 _byte_map 则是用于标记的卡表字节数组,我们可以看到其对应的类型为 jbyte(typedef signed char ...

Serialization exceptions can occur in three places:SerializedLambda.readResolve,ObjectStreamClass.<init>andReflectionFactory.newConstructorForSerialization. In each case, the potential serialization-specific exceptions can be reproduced in Native Image, and don't require specific build-time support. The excep...
