RFR: 8278123: serviceability/dcmd/vm/ClassLoaderStatsTest.java failing with java.lang.AssertionError: Should have a hidden class [v3]

[Leonid Mesnik]

> The test failed if GC happens somewhere between
> Class<?> c = Class.forName("TestClass", true, dummyloader);
> and
> OutputAnalyzer output = executor.execute("VM.classloader_stats");
> 
> The fix is to make hc static as Chris proposed. 
> 
> To verfiy fix I add System.gc() before executor.execute("VM.classloader_stats");
