Unwanted execution of ImmutableEnumChecker by enabling Immutable check

[mihalyr]

Hi,

there is most likely some mistake in how these two checks are configured leading to false activation of unintended checks:

Immutable

• Type declaration annotated with @Immutable is not immutable
• https://errorprone.info/bugpattern/Immutable
• Severity: ERROR by default

ImmutableEnumChecker

• Enums should always be immutable
• https://errorprone.info/bugpattern/ImmutableEnumChecker
• Severity: WARNING by default
• ⚠ Alternate names: Immutable

The ImmutableEnumChecker warning declares the same name as the Immutable error.

Given a code that has -XepDisableAllChecks -XepDisableAllWarnings -Xep:Immutable:ERROR, trying to enable the former Immutable error for checking the @Immutable annotated types, it mistakenly activates the ImmutableEnumChecker at an ERROR level leading to unwanted failures.
