Open the project in NetBeans, select configuration gen_sherman2_6 and Java platform jdk1.7.0-b84/fastdebug and build it.
java/lang/CharacterNames6.java has an assert statement at line 103. It's span accross three lines. But when I look at the compiled bytecode (javap -private -c -l java/lang/CharacterNames6), the LineNumberTable of initNames() method is:
   ...
   line 101: 188
   line 105: 199
   ...
Code index 199 is the *beginning* of the assert statement, which starts at line 103. Therefore IMHO line 103 should map to code index 199.
