are both consistently failing on openj9 builds (Hotspot unaffected)

• test category, openjdk
• OS/architecture, all platforms

15:35:14  openjdk version "1.8.0_232"
15:35:14  OpenJDK Runtime Environment (build 1.8.0_232-201909030344-b03)
15:35:14  Eclipse OpenJ9 VM (build master-cc749fa0a, JRE 1.8.0 Linux amd64-64-Bit Compressed References 20190903_405 (JIT enabled, AOT enabled)
15:35:14  OpenJ9   - cc749fa0a
15:35:14  OMR      - 5628a974
15:35:14  JCL      - efd729851b based on jdk8u232-b03)

Optional info

• intermittent failure (no):
• new test:
• Possibly related to JTReg Test Failure: java/lang/invoke/CallerSensitiveAccess.java #6768
• setAccessbile() appears to be broken for openj9. I have not yet confirmed this however.

I expect this test is using internals that don't apply to OpenJ9

 java.lang.NoSuchFieldException: debugName
15:37:07  	at java.lang.Class.getDeclaredField(Class.java:820)

I also suspected this was the case based on similar issues (#6700, #6660). I'll close this and add it to the permanent exclusions list

java/lang/invoke/LFCaching/LFSingleThreadCachingTest.java also fails in the same way. Will exclude this too
