------------------------------------
This looks trivial to fix. Why hasn't it been done?

> In class com.ibatis.common.beans.ClassInfo, when NO SecurityManager is
> installed, each time the method ClassInfo#canAccessPrivateMethods() is
> called, a NullPointer exception is thrown, it would be more performant to
> test for nullity:
> private boolean canAccessPrivateMethods() {
> try {
> SecurityManager manager = System.getSecurityManager();
> if (manager == null)
> {
> return true;
> }
> manager.checkPermission(new ReflectPermission("suppressAccessChecks"));
> return true;
> } catch (SecurityException e) {
> return false;
> } catch (NullPointerException e) {
> return true;
> }
> }
