Import of large Java files (with either long blocks or classes with hundreds of members) may cause stack overflow

[codemanyak]

Attempting to import file "lu.fisch.structorizer.gui.Menu.java" reveals the severe risk of a stack overflow during the diagram building phase. It is due to the awkwardness of recursively processing left-recursive reduction rules. Particularly class bodies and statements blocks are prone to calamity. Though most these sequences hardly exceed some 20 elements, some may have dangerous sizes as the followong example snippets from a test log corroborate:

• Doing block of type 148 with length 372
• Doing block of type 236 with length 360
• Doing block of type 236 with length 117

The solution is to convert the reduction tree into a reduction stack first and then to process its element reductions sequentially in a loop.
