LibGraal lookup Java Field Issue

[HumphreyHCB]

As requested by @dougxc on Slack,
I’m opening my changes as a PR to help illustrate what I’m doing.

The issue is coming from:
context.getMetaAccess().lookupJavaField(BuboCache.class.getField(FieldName))
being performed in a phase while in LibGraal mode.

All of this works in JarGraal,
but when I switch over, I get the following crash.

java.lang.NoSuchFieldException: TimeBuffer
