* Note: we try to trigger bugs by enforcing the JVM to use zero-based mode. To increase the chance of zero-based
|
|
* mode, we start with CDS disabled, a small class space and a large (albeit uncommitted, to save memory) heap. The
|
|
* JVM will likely place the class space in low-address territory.
|
|
* (If it does not manage to do this, the test will still succeed, but it won't alert us on regressions)
