  1. PODoes scala affect AspectJ/Spring AOP at all? I'm having a thread locking problem when running tests when an @Configurable is being called
    text
    copied!<p>I have a strange problem where when I run my tests using maven, it locks whenever a test method calls into an object with an annotation @Configurable. I can run the tests fine in IDEA using the AspectJ Weaver plugin (remarkably), but I cannot do it with maven (whether I execute them in IDEA or just in a terminal).</p> <p>Even weirder, if I press ctrl-c, it does not kill the process. It just keeps a 500meg process in memory for eternity until I kill it using the System Monitor in Ubuntu.</p> <p>This problem never happened until I added Scala to my Java project. Note, I'm not compiling Scala code - just including jars that were compiled with scala and I'm including the Scala compiler/library jars as part of the classpath.</p> <p>Basically, Maven will run a bunch of tests and then hang:</p> <pre><code>Tests run: 2, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.206 sec Running jobprep.domain.student.ActiveQuestionTests Tests run: 26, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.065 sec Running jobprep.domain.sysadmin.WebpageValidationTests Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.225 sec Running jobprep.domain.question.openended.OpenEndedStudentSubmissionDeserializerTests </code></pre> <p>When it comes to OpenEndedStudentSubmissionDeserializerTests, it freezes. It would appear that the reason why is that OpenEndedStudentSubmissionDeserializer is using @Configurable. If I comment out the test class and run the tests again, it'll just freeze on the next test class that uses @Configurable.</p> <p><strong>EDIT</strong>: It's interesting enough, if I tell maven to just run the tests in the "jobprep.domain.question.openended" package, it works 100%. If I tell it to run everything in "jobprep.domain", it still works! If I tell it to run everything in "jobprep", then the problem happens.</p> <p>Is there something I should be aware of with Scala, AspectJ, Spring, etc. when it comes to this root package?</p> <p>In Maven, if I tell surefire to load only a subset of my tests, it works. 893 out of the 1096 tests in my test suite will <strong>run</strong> and <strong>pass</strong>. This isn't perfect though because I need to get the remaining tests to work still:</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-surefire-plugin&lt;/artifactId&gt; &lt;version&gt;2.6&lt;/version&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;junit&lt;/groupId&gt; &lt;artifactId&gt;junit&lt;/artifactId&gt; &lt;version&gt;4.8.1&lt;/version&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;configuration&gt; &lt;includes&gt; &lt;include&gt;**/dao/*Tests.java&lt;/include&gt; &lt;include&gt;**/domain/*Tests.java&lt;/include&gt; &lt;include&gt;**/domain/**/*Tests.java&lt;/include&gt; &lt;include&gt;**/service/*Tests.java&lt;/include&gt; &lt;include&gt;**/service/**/*Tests.java&lt;/include&gt; &lt;include&gt;**/validator/*Tests.java&lt;/include&gt; &lt;/includes&gt; &lt;excludes&gt; &lt;exclude&gt;**/Abstract*Tests*.java&lt;/exclude&gt; &lt;exclude&gt;**/DatabaseTests.java&lt;/exclude&gt; &lt;exclude&gt;**/ControllerTests.java&lt;/exclude&gt; &lt;exclude&gt;**/ValidationTests.java&lt;/exclude&gt; &lt;/excludes&gt; &lt;skipTests&gt;false&lt;/skipTests&gt; &lt;/configuration&gt; &lt;/plugin&gt; </code></pre> <p>It sucks that I have to be this fine-grained, but I don't know any other way to go about solving this problem. </p> <p>Anyway, once I add this line, it starts to lock up at the OpenEndedSubmissionDeserializerTests like before:</p> <pre><code>&lt;include&gt;**/controllers/*Tests.java&lt;/include&gt; </code></pre> <p>You know what's curious though? If I run the tests for controllers <em>only</em>, it works! Bloody hell! Could this mean they both run separately, but not together?!?</p> <p>Anyway, when maven frezes, if I press CTRL-\ in linux instead of CTRL-C, this is what happens:</p>
