The javax/management/remote/mandatory/notif/ListenerScaleTest.java test fails intermittently - this change preserves the function of the test, while minimizing/removing intermittent failures. Specifically, the test exists to check that notification work does not scale linearly with number of MBeans, so it calculates a ratio of the time taken with one, and with 20,000 MBeans. We can increase the point at which that calculated ratio is considered a failure: original commit chooses 2500. Ran GHA Sanity Checks (1 unrelated test failure - java/lang/ProcessBuilder/Basic.java#id0) and adjusted test (passed). Patch is clean.

This pull request has now been integrated.
