java - Eclipselink Modelgen processor and Spring Security -

i trying use spring security in project use eclipselink modelgen processor generate static meta model. when try strange compilation errors like:

> java.lang.runtimeexception: com.sun.tools.javac.code.symbol$completionfailure: class file org.springframework.security.ldap.defaultspringsecuritycontextsource not found 

even though not use ldap. if add jars other errors missing sl4j, missing openid, etc etc. if exchange used modelgen processor hibernate implementation compiles without problems.

i found minimal project reproduce problem:

myenity.java

@entity public class myentity {      private string name;     private long id;      public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }      public long getid() {         return id;     }      public void setid(long id) {         this.id = id;     }  } 

securityconfig.java

public class securityconfig extends websecurityconfigureradapter {  } 

build.gradle

apply plugin: 'war' apply plugin: 'maven'  group = 'com.demo' version = 'alpha'  sourcecompatibility = 1.8 targetcompatibility = 1.8  [compilejava, compiletestjava]*.options*.encoding = 'utf-8'  repositories {     maven { url "http://repo.maven.apache.org/maven2" }     maven { url "http://download.eclipse.org/rt/eclipselink/maven.repo/" } }   dependencies {     compile 'org.eclipse.persistence:org.eclipse.persistence.jpa.modelgen.processor:2.6.0'//latest stable @06.07.2015       compile "org.springframework:spring-beans:4.1.6.release"     compile "org.springframework:spring-core:4.1.6.release"     compile "org.springframework:spring-web:4.1.6.release"     compile "org.springframework:spring-context:4.1.6.release"     compile 'org.springframework:spring-jdbc:4.1.6.release'     compile 'org.springframework.security:spring-security-core:4.0.2.release'     compile 'org.springframework.security:spring-security-web:4.0.2.release'     compile 'org.springframework.security:spring-security-config:4.0.2.release'      providedcompile 'javax:javaee-api:7.0@jar' } 

as remove

a) @entity myentity

or

b) extends websecurityconfigureradapter security config

or

c) use compile 'org.hibernate:hibernate-jpamodelgen:4.3.10.final' instead of compile 'org.eclipse.persistence:org.eclipse.persistence.jpa.modelgen.processor:2.6.0'

everything compiles without problems.

so why use of eclipselink modelgen processor cause compilation errors?
