Subject: [PATCH] Fix regex mistake in CB NBT int deserialization
|
|
|
|
The existing regex is too open and allows for the absence of any actual
|
|
number data, detecting an NBT entry of just the letter "i" in upper or
|
|
lower case. This causes a single-character NBT entry to be processed as
|
|
an integer ending in "i", passing an empty String to to Integer.parseInt,
|
|
triggering an exception in loading the item.
|
|
|
|
This commit forces numbers to be present prior to the ending "i"
|
|
letter.
