Regression test for b/62237378
|
|
|
|
It was possible for the JVMTI class redefinition to encounter a use-after-free
|
|
bug if there had been an attempted redefinition that failed due to a
|
|
verification error in the same class loader. Actually encountering the bug
|
|
required that a later redefinition happen to get the same native pointer for its
|
|
dex-file as the failed redefinition.
|
|
|
|
Hitting this use-after-free can cause many strange outcomes, from CHECK failures
|
|
to segfaults to incorrect redefinition failures (for example on buggy builds
|
|
this test will fail a DCHECK on debug builds, segfault on x86_64 hosts and have
|
|
redefinition of LDexCacheSmash$Transform; erroneously fail with
|
|
JVMTI_ERROR_FAILS_VERIFICATION on 32 bit hosts).
