/**

* This class contains information regarding when a VerifyError is thrown

|
* in the verifier. Most of the data is informational-only, and can be
|
|
* used to track down where and why VerifyErrors are thrown. As such it
|
|
* is possible the information may go out-of-date.
|
|
*
|
|
* The only fields used for the purpose of testing is the 'caseName' and
|
|
* the 'message'. The 'caseName' corresponds to a classfile which exhibits
|
|
* the VerifyError, and the 'message' is a regular expression which we expect
|
|
* to match the verify error message. If the 'message' doesn't match what
|
|
* we expect, it warrents investigation to see if we are still triggering
|
|
* the VerifyError that we expect. It could simply just be that the message
|
|
* changed, which is fine.
|
|
*
|
|
* Some cases are not testable, either because the code is probably unreachable
|
|
* or the test classfile would be too onerous to create. These cases are
|
|
* marked with 'testable' == false, and the test runner will skip them.
