Performance improvement by adding local cache for
MultiParentClassLoader#loadClass
----------------------------------------------------------------------------------
Key: XBEAN-203
URL: https://issues.apache.org/jira/browse/XBEAN-203
Project: XBean
Issue Type: Improvement
Components: classloader
Affects Versions: 3.7
Reporter: Gert Vanthienen
While profiling for performance issues on ServiceMix, we noticed a lot of time
was spent waiting for the object lock to access MultiParentClassLoader's
loadClass() method, especially when using things like JAXP. We managed to get
significant improvements by adding a local cache to avoid the synchronized
method invocation for previously loaded classes.
