SonarQube fails to restart during plugin development

I'm developing a plugin for SonarQube 4.5.4 / 5.0.1. I would like to use sonar-dev plugin to upload a JAR file and quickly restart SQ server. Plugin uses REST API (/api/system/restart), which is enabled by setting sonar.dev=true property.

Here's config:

<plugin>
    <groupId>org.codehaus.sonar</groupId>
    <artifactId>sonar-dev-maven-plugin</artifactId>
    <version>1.8</version>
    <configuration>
        <sonarHome>F:\sonarqube-5.1\sonarqube-5.1</sonarHome>
    </configuration>
</plugin>

The problem is that server crashes after each restart attempt and I have to restart it manually, which is frustrating and drains my productivity. Here's stacktrace that is returned on each following request after "restart".

org.jruby.exceptions.RaiseException: (NoMethodError) undefined method `controllers' for nil:NilClass
    at org.jruby.RubyKernel.method_missing(org/jruby/RubyKernel.java:255)
    at RUBY.method_missing(F:/sonarqube-5.1/sonarqube-5.1/web/WEB-INF/gems/gems/activesupport-2.3.15/lib/active_support/whiny_nil.rb:52)
    at RUBY.add_java_ws_routes(F:/sonarqube-5.1/sonarqube-5.1/web/WEB-INF/config/../lib/java_ws_routing.rb:34)

    at RUBY.serve_rails(file:/F:/sonarqube-5.1/sonarqube-5.1/lib/server/jruby-rack-1.1.13.2.jar!/rack/adapter/rails.rb:34)
    at RUBY.call(file:/F:/sonarqube-5.1/sonarqube-5.1/lib/server/jruby-rack-1.1.13.2.jar!/rack/adapter/rails.rb:39)
    at RUBY.call(file:/F:/sonarqube-5.1/sonarqube-5.1/lib/server/jruby-rack-1.1.13.2.jar!/rack/handler/servlet.rb:22)

And here's what happens in logs starting from line 71.

According to @Simon Brandhof, it may be connected with class loader, that locks files. Any clue or workaround be be much appreciated.

The Java plugin seems to lock its classloader. Uninstalling it, by deleting extensions/plugins/sonar-java-plugin-3.0.jar, should fix the issue.
