manuc66 created GROOVY-7804:
-------------------------------
Summary: @CompileStatic/@TypeChecked unexpected
NullpointerException compiler bug
Key: GROOVY-7804
URL: https://issues.apache.org/jira/browse/GROOVY-7804
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 2.4.6
Environment: Windows, jdk1.8.0_60
Reporter: manuc66
Those code produce compiler bug exception (see below) when @CompileStatic or
@TypeChecked is used :
@CompileStatic
class KeywordApiMain {
static main(args) {
Optional.of("MH370").orElseThrow({ -> new RuntimeException() });
}
}
@CompileStatic
class KeywordApiMain {
static main(args) {
Optional.of("MH370").orElseThrow { -> new RuntimeException() };
}
}
Those code just produce the expected behaviour when compiled and run without
the annotation. The workaround is simplifying the code to this :
class KeywordApiMain {
static main(args) {
Optional.of("MH370").orElseThrow { new RuntimeException() };
}
}
Error:Groovyc: BUG! exception in phase 'instruction selection' in source unit
'-------\XXXX.groovy' unexpected NullpointerException
