Given 99.9% of the tests don't try to initialize "caps" but instead do the memset, I would suggest it is perfectly fine to delete the initializer and remove the comments related to AIX/xlclang.

You may also need to check
hotspot/jtreg/runtime/jni/FastGetField/libFastGetField.c 
hotspot/jtreg/compiler/jsr292/cr8026328/libTest8026328.c
which have a similar usage for the callbacks structure.
