Patch a tableswitch instruction's low value to be greater than a high value,
previously, javap will not print any previous instruction and report
problematic address/bci to be 0. This is because the iteration of bound models
require first collecting all data into a buffer list. We call the eager
`forEach` instead to avoid this problem.
Before:
$ javap -c BadSwitch.class
Compiled from "BadSwitch.java"
final class BadSwitch {
static void work(int);
Code:
Error: error at or after byte 0
}
Now:
$ $localjdk2/bin/javap -c BadSwitch.class
Compiled from "BadSwitch.java"
final class BadSwitch {
static void work(int);
Code:
0: iload_0
Error: error at or after address 1: Invalid tableswitch values low: 9 high: 5
}
