Adrien Guichard created GROOVY-12172:
----------------------------------------
Summary: Groovy 5.0.7 fail to compile or startup with
UnsupportedOperationException
Key: GROOVY-12172
URL: https://issues.apache.org/jira/browse/GROOVY-12172
Project: Groovy
Issue Type: Bug
Components: build
Affects Versions: 5.0.7
Reporter: Adrien Guichard
When compiling the following code:
{code:java}
import groovy.transform.CompileStatic
@CompileStatic
class X1 {
Long id
}
@CompileStatic
class X2 {
Long id
}
@CompileStatic
class Y {
Long computeId(Object test) {
if (test instanceof X1 || test instanceof X2) {
return test['id'] as Long
null
}
}
}
println new Y().computeId(new X1(id: 12))
{code}
Groovy 5.0.7 fails with MultipleCompilationErrorsException
, but Groovy 4.0.32 is OK:
{code:java}
~/dev/groovy
❯ ./groovy-4.0.32/bin/groovy test.groovy
12
~/dev/groovy
❯ ./groovy-5.0.7/bin/groovy test.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during instruction selection:
java.lang.UnsupportedOperationException {code}
It is not a code pattern we tend to use often, but on a huge code base, it can
be tricky to narrow done this kind of issue.
A simple workaround would be to split the if.
Thanks for your support,
Adrien
