[foreign] RFR: 8223641: Run jextract with --log FINE cause UnsupportedOperationException

[Henry Jen]

Hi,

Please review the trivial webrev[1] that fix usage of unsupported JType.Function.getSourceSignature that cause the UOE[2].

Because JType.Function doesn’t have information about function name, thus a proper implementation if not viable.

Cheers,
Henry
