Xiaoguang Wang updated GROOVY-8470:
-----------------------------------
Description:
cat a.groovy
{code:java}
enum EnumA {
EA(EnumB.EB) // without a semicolon here, the groovyc enters dead loop
enum EnumB { EB }
private EnumA(EnumB enumB) {
}
}
{code}
Run:
groovyc a.groovy
It hangs in:
{code:java}
"main" #1 prio=5 os_prio=31 tid=0x00007fe32c001800 nid=0x2403 runnable
[0x0000700008b92000]
