SEC-1423: Inefficient Pointcut Expression parsing in ProtectPointcutPostProcessor.java

[spring-projects-issues]

Tudor Malene (Migrated from SEC-1423) said:

The ProtectPointcutPostProcessor.postProcessBeforeInitialization method parses each pointcut expression for each method of the present bean until it finds a match, which is highly inefficient.

The parsed pointcutExpressions can be cached in a LinkedHashSet when the pointcut is added ( see patch ), thus avoiding the parsing of the same expression for each method of the current bean.

Good idea. I've updated the code to add caching for both 3.1.x and 3.0.x.
