> An incomplete fix for the NPE bugs in AbstractJavadocMojo.java
> --------------------------------------------------------------
>
> Key: MJAVADOC-342
> URL: https://jira.codehaus.org/browse/MJAVADOC-342
> Project: Maven 2.x Javadoc Plugin
> Issue Type: Bug
> Reporter: Guangtai Liang
> Priority: Critical
>
> The fix revision 554202 was aimed to remove an NPE bug on the returned value
> of "getJavadocDirectory()" in the method "getSourcePaths " of the file
> "/maven/plugins/trunk/maven-javadoc-plugin/src/main/java/org/apache/maven/plugin/javadoc/AbstractJavadocMojo.java"
> , but it is incomplete.
> Since the returned value "getJavadocDirectory()" could be null during the
> runtime execution, its value should also be null-checked before being
> dereferenced in other methods.
> The buggy code locations the same fix needs to be applied at are as bellows:
> Line 2401 of the method "copyJavadocResources";
> Line 1505 of the method "getSourcePaths".
