LruCacheClassPathRepository
URL: https://github.com/apache/commons-bcel/pull/28
[BCEL-320](https://issues.apache.org/jira/browse/BCEL-320)
[BCEL OutOfMemoryError
Example](https://github.com/suztomo/bcel-oome-example) is an example of
OutOfMemoryError caused by scanning many JAR files using BCEL
ClassPathRepository and MemorySensitiveClassPathRepository. This newly proposed
LruCacheClassPathRepository does not fail for the case.

> (This ticket is derivation from
> [BCEL-317|https://issues.apache.org/jira/browse/BCEL-317], which I found
> creating ConstantUtf8 cache is not straightforward under current
> ClassPathRepository design.)
> We use BCEL library in
> https://github.com/GoogleCloudPlatform/cloud-opensource-java . Thank you for
> great library.
> h1. Background
> Our use of BCEL ClassPathRepository and MemorySensitiveClassPathRepository
> causes OutOfMemoryError when they scan many (~200) JAR files. Initially I
> thought this problem could be fixed by
> [BCEL-317|https://issues.apache.org/jira/browse/BCEL-317], but it turned out
> that it's not straightforward under current design. Instead of focusing on
> ConstantUtf8, I decided to use my own custom ClassPathRepository that uses
> LRU cache internally to hold JavaClass instances. It worked.
> This ticket is to contribute the idea to BCEL library so that other users can
> benefit from it.
> h1. Test Case
> This GitHub project is a example of OutOfMemoryError caused by scanning many
> JAR files using BCEL ClassPathRepository and
> MemorySensitiveClassPathRepository:
