> [JDK-8375548](https://bugs.openjdk.org/browse/JDK-8375548) added support for compiler replay but only tested with cases where classes can actually be loaded. When some classes cannot be loaded (for example, due to missing class files), we crash with a null pointer when run with `+ReplayIgnoreInitErrors`: `parse_klass()` returns `null` for non-loadable classes. Then, we access it with `k->is_objArray_klass()` without checking for null and we crash. This patch adds a simple null-check to fix the problem.
