[Guoxiong Li]

> Hi all,
> 
> This patch increases the delay time of the test `TestAbortOnVMOperationTimeout` 
> so that it can pass on the low performance devices (such as my local riscv64 dev board).
> 
> And I adjust the gc log options to get more gc log message which is useful to
> inspect the issue [JDK-8296819](https://bugs.openjdk.org/browse/JDK-8296819).
> 
> Thanks for the review.
