Tool Component - Rules not reading float properly?

Summary

When trying to load the TestTool item below, I get an "Error loading item 'TestTool'." I have debugging stack trace below as well.

Steps to reproduce

Install TestTool item on your server, do /mm reload and see the item fails to load. If you remove the "Rules" section of the config, the tool does load.

TestTool:
  Id: COD
  Display: '<purple>Obsidian Destroyer'
  Tool:
    DamagePerBlock: 1
    DefaultMiningSpeed: 5.0
    Rules:
      - materials: "OBSIDIAN,CRYING_OBSIDIAN"
        speed: 10000.0
        isCorrectForBlock: true

Proposed fixes

Take a look at the double/float parser and the rules section of the tool component.
