RFR: 8366694: Test JdbStopInNotificationThreadTest.java timed out after 60 second [v2]

[SendaoYan]

> Hi all,
> 
> Test com/sun/jdi/JdbStopInNotificationThreadTest.java fails "Exception thrown during test execution: waitForPrompt timed out after 60 seconds" after JDK-8260555 change the default timeout factor from 4 to 1. Before JDK-8260555, the "waitForPrompt timed out" value if calculate from `Utils.adjustTimeout(60000)` in [test/jdk/com/sun/jdi/lib/jdb/Jdb.java](https://github.com/openjdk/jdk/blob/master/test/jdk/com/sun/jdi/lib/jdb/Jdb.java#L80), it will [multiply the timeout factor](https://github.com/openjdk/jdk/blob/master/test/lib/jdk/test/lib/Utils.java#L468) . After JDK-8260555 change the timeout factor from 4 to 1, so this timeout value should be ajusted.
> 
> Change has been verified locally, risk is low.

  Use addDebuggeeOptions(-Xmx64) to make test run quickly, instead of add timeout value
