xxx? second half of the page |
Finally the Application classloader is created, which is responsible for loading in user classes from the defined classpath. Some texts unfortunately refer to this as the “System” classloader. This term should be avoided, for the simple reason tht it doesn’t load the system (the Bootstrap classloader does). The Application classloader is encountered extremely frequently, and it has the Extension loader as its parent. |

Printed | Page 83 First and second list |
There are two lists on the page which are both numbered 1 and 2, however, the text refers to them by letters A-D. I believe the first list should be A, B, instead of 1, 2, and the second list should be C, D, instead of 1, 2. |

'starting from the mean' should surely be 'starting from the median'. The samples shown are percentiles, and the 50% percentile is the median _not_ the mean; e.g. if only the slowest samples get even slower, this affects the mean but not the median. It might be worth the authors pointing this out as another reason the mean isn't very useful. |

Printed | Page 146 Figure 7-1. |
I think Figure 7-1 is confusing. According to Tri-colored Marking algorithm, the nodes which are directly reachable from root sets are colored gray at the beginning. Then, the gray nodes turn to black and the nodes which they reference are colored gray. This continues until no gray nodes are left. |

The list of “Initial Mark” and “Remark” has an asterisk in front of “Remark”. This asterisk probably shouldn’t be there. |
