------------------------------------
Summary: ArrayStoreException assigning GStringImpl to String[]
when using Indy
Key: GROOVY-7494
URL: https://issues.apache.org/jira/browse/GROOVY-7494
Project: Groovy
Issue Type: Bug
Components: groovy-runtime
Affects Versions: 2.4.3
Environment: Windows 7; Java 8
Reporter: Ken Scoggins
While upgrading a software baseline from Java 7/Groovy 2.0.2 to Java 8/Groovy
2.4, it appears that assigning a GString with an embedded variable reference to
a String array is broken when using Indy. The following example demonstrates
this issue:
{code}
int a = 1
String[] fubar = new String[1]
fubar[0] = "Item $a"
println fubar
{code}
Without Indy, it works just fine:
{panel}
/c/test$ groovy GroovyIndyBug.groovy
[Item 1]
{panel}
With Indy, we get the ArrayStoreException
{panel}
/c/test$ groovy -indy GroovyIndyBug.groovy
Caught: java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
at GroovyIndyBug.run(GroovyIndyBug.groovy:3)
{panel}
I tried various other assignment methods and this appears to be the only one
with the issue. Oddly, even doing the same assignment, but at creation time
instead of after, works just fine. Some of the other related scenarios I tried
are:
{code}
int a = 1
String[] foo = ["Assigned At Creation $a"]
println foo
foo[0] = "No Embedded Variable"
println foo
foo[0] = "as String $a" as String
println foo
foo[0] = "BROKEN $a"
println foo
{code}
With Indy:
{panel}
/c/test $ groovy -indy GroovyIndyBug.groovy
[Assigned At Creation 1]
[No Embedded Variable]
[as String 1]
Caught: java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
java.lang.ArrayStoreException: org.codehaus.groovy.runtime.GStringImpl
at GroovyIndyBug.run(GroovyIndyBug.groovy:12){panel}
