Xjc with generateEpisode=false throws Exception

[isotes]

The error can be reproduced with the integration test: In src/it/xjc-main/pom.xml, add <generateEpisode>false</generateEpisode> to the configuration (after <packageName>com.example.myschema</packageName>). With this, the integration test fails. If additionally @project.version@ is replaced by 2.5.0, it is possible to just build the project in src/it/xjc-main which shows the exceptions in the log below.

Despite the info message 'Created EpisodePath', the mentioned path src/it/xjc-main/target/generated-sources/jaxb/META-INF/JAXB does not exist and my guess is that then the creation of a file fails. However, I would expect that with generateEpisode=false neither the file nor the directory should be created.
