File: org.scala-ide.sdt.aspects/src/scala/tools/eclipse/contribution/weaving/jdt/jcompiler/ExtendedResourceDelta.java line 159
By froden:

NullPointerException happens here because the resource has a different base path that does not match this.getResource:
this.getResource(): P/web-server
newResource was (at first entry to this method): L/parent/web-server/src/test/java/org/apache/commons/httpclient/contrib/ssl/EasyX509TrustManager.java

This is the wrong resource and should probably be ignored. Please see the other comment above.
