PathMatchingResourcePatternResolver(ClassLoader classLoader) [SPR-5264]

[spring-projects-issues]

Peter Rietzler opened SPR-5264 and commented

The method documentation says:

• @param classLoader the ClassLoader to load classpath resources with,
• or <code>null</code> for using the thread context class loader
  ...
  public PathMatchingResourcePatternResolver(ClassLoader classLoader) {

The following code throws a NullPointerException:

new PathMatchingResourcePatternResolver(null).getResources("*/**");

Indeed, we need to obtain the thread context ClassLoader at the time of actual resource access there. Fixed as of 3.0 M2.
