34 * This class contains information regarding when a VerifyError is thrown | |
35 * in the verifier. Most of the data is informational-only, and can be | |
36 * used to track down where and why VerifyErrors are thrown. As such it | |
37 * is possible the information may go out-of-date. | |
38 * | |
39 * The only fields used for the purpose of testing is the 'caseName' and | |
40 * the 'message'. The 'caseName' corresponds to a classfile which exhibits | |
41 * the VerifyError, and the 'message' is a regular expression which we expect | |
42 * to match the verify error message. If the 'message' doesn't match what | |
43 * we expect, it warrents investigation to see if we are still triggering | |
44 * the VerifyError that we expect. It could simply just be that the message | |
45 * changed, which is fine. | |
46 * | |
47 * Some cases are not testable, either because the code is probably unreachable | |
48 * or the test classfile would be too onerous to create. These cases are | |
49 * marked with 'testable' == false, and the test runner will skip them. | |
