Bug or performance issue on InvocationFilter

[mehdijk]

Hi
I make a Spoon model for HSQLDB 1.8.0.9 and try to find invocation for some CtExecutable s . It works well for most of the items and it finds invocation list in 3-4 seconds. However for 3 methods, it takes so long and the invocation list is empty. The methods are:
public void org.hsqldb.util.DatabaseManagerSwing$StatementExecRunnable.run() takes 868 s
public void org.hsqldb.persist.LockFile$HeartbeatRunner.run() takes 111 s
void org.hsqldb.lib.HsqlTimer$Task.cancel() takes 89 s
This is my code:
List<CtInvocation<?>> invocationList = rootPack.getElements(new InvocationFilter(ctexe.getReference()));
Is there any bug or performance issue?

Hi,

I confirm the performance issue. This is probably caused by the method CtExecutableReference#isOverriding which uses reflection when it is needed.

When you want to get all invocations of a CtMethod inside your source code, you don't need the reflection, so the performance is good.

But when you want all invocations of a method declared in a superclass which isn't present in the source classpath, you need to use the reflection for each CtExecutableReference of your project.

I have maybe a solution, I'll let you know.
