Forget it, it's a buggy testcase. In here:
public static void main(String[] args)
{
try
{
a();
}
catch (Exception x)
{
StackTraceElement[] trace = x.getStackTrace();
checkTrace(trace);
}
}
static void a()
{
new Inner();
}
a() gets inlined into main(), so the stacktrace is only three elements
in size:
[Ljava.lang.StackTraceElement;@2aaaae240f78
{
java.lang.StackTraceElement@2aaaaab0b6c0
{
boolean isNative = false,
java.lang.String fileName = "StackTrace2.java",
java.lang.String methodName = "doCrash",
java.lang.String declaringClass = "StackTrace2$Inner",
int lineNumber = 33,
}, java.lang.StackTraceElement@2aaaaab0b690
{
boolean isNative = false,
java.lang.String fileName = "StackTrace2.java",
java.lang.String methodName = "<init>",
java.lang.String declaringClass = "StackTrace2$Inner",
int lineNumber = 28,
}, java.lang.StackTraceElement@2aaaaab0b660
{
boolean isNative = false,
java.lang.String fileName = "StackTrace2.java",
java.lang.String methodName = "main",
java.lang.String declaringClass = "StackTrace2",
int lineNumber = 21,
},
}
It's safe to inline methods within the same class -- they can't have
different protection domains, for example.
