I'm using spotbugs-maven-plugin 4.0.0 (+ spotbugs 4.0.2 dependency).
The problem is that it cannot recognize Java 14 records.
Every time when it finds a record or a class that uses that record, it prints a long stacktrace.

How can I get rid of these detailed exceptions?
Though the plugin's latest release read the support through JDK-15, the ASM support for preview features require 8.0+ version while the library is still on 7.3.1.
That said, the changes to their deployable branch should fix this. Specifically the difference in:
- <asm.version>7.3.1</asm.version>
+ <asm.version>8.0.1</asm.version>
So just wait for the next version while requesting them to release soon. :)
