    Field
    Description
    protected static final int[]
    OPCODE_BLACKLIST
    List of opcodes which must not appear in a class initialiser, mainly a sanity check so that if any of the specified opcodes are found, we can log it as an error condition and then people can bitch at me to fix it.

    • OPCODE_BLACKLIST

      protected static final int[] OPCODE_BLACKLIST
      List of opcodes which must not appear in a class initialiser, mainly a sanity check so that if any of the specified opcodes are found, we can log it as an error condition and then people can bitch at me to fix it. Essentially if it turns out that field initialisers can somehow make use of local variables, then I need to write some code to ensure that said locals are shifted so that they don't interfere with locals in the receiving constructor.
