setGlobalLimit

int setGlobalLimit(int globalLimit)

Sets a hard limit on how many bytes we can continue to read while parsing a message from current position. This is useful to prevent corrupted or malicious messages with wrong length values to abuse memory allocation. Initially this limit is set to Integer.MAX_INT, which means the protection mechanism is disabled by default. The limit is only useful when processing streams. Setting a limit for a decoder backed by a byte array is useless because the memory allocation already happened.
