NullPointerException thrown during analysis

After Upgrading from 2.12.1 I get this error during analysis:

C:\Users\axel\IdeaProjects\utility\utility\build\generated-sources\cabe\com\dua3\utility\math\MathUtil.java:478: error: An unhandled exception was thrown by the Error Prone static analysis plugin.

I got a similar error and stack in 2.15.0

case VERTICAL_1 -> ItemFacetMapper.INSTANCE::facetEntryToVerticalGraphQLObject;

I'm seeing the same NPE with switch expressions on java 17 and errorprone 2.15.0. It sounds like 7504736 fixes it, but the 2.15.0 release on Maven Central doesn't have it. Any idea when this fix will be released?

Thanks
