NPG: Remove ConstantPool::lock

    XMLWordPrintable

Details

    • b23

    Description

      The use of locks of constant pool could raise memory usage (see JDK-8014910) or cause deadlock (see JDK-8008962).

      Let's try to remove the lock altogether. Much of the existing operation (see CPSlot class) is already lock free.
