Infinite Recursion Intention

this code is wrongly highlighted as infinite recursion,
the try-catch at beginning causes the problem (when removing the try-catch IDEA no longer thinks it recurses infinitely)

//dummy code:
private void rec(BasePageConfig pageConfig)
{
try
{
new File("c:/").getCanonicalFile();
}
catch (IOException e)
{

}
final List subpages = pageConfig.getSubpages();
for (int j = 0; j < subpages.size(); j++)
{
BasePageConfig pc = (BasePageConfig) subpages.get(j);
rec(pc);
}
}
