--------------------------------------
Summary: EnumSet .plus() regression in Groovy 4
Key: GROOVY-12020
URL: https://issues.apache.org/jira/browse/GROOVY-12020
Project: Groovy
Issue Type: Bug
Affects Versions: 4.0.32
Reporter: Anton Panikov
EnumSet.plus() method stopped working after upgrading to Groovy 4, but it is
working in Groovy 5. All tests done using JDK 25, although I tried 11 with the
same result.
It is a runtime exception and the code need to access newly created EnumSet:
{code:groovy}
package test
import groovy.transform.CompileStatic
enum EnumTest {
ONE,
TWO,
THREE,
FOUR,
FIVE,
SIX,
SEVEN,
EIGHT,
NINE
public static final EnumSet<EnumTest> firstSet = EnumSet.of(ONE, TWO,
THREE, FOUR, FIVE)
public static final EnumSet<EnumTest> secondSet = firstSet + SIX
}
@CompileStatic
class Application {
static void main(String[] args) {
println EnumTest.secondSet
println 'ok'
}
}
{code}
It is working fine in Groovy 3.0.25 and 5.0.6. But in Groovy 4.0.32, it is
throwing an exception:
{code:groovy}
Exception in thread "main" java.lang.ExceptionInInitializerError
