-----------------------------
> GroovyCodeSource(URL) can leak a file handler
> ---------------------------------------------
>
> Key: GROOVY-8056
> URL: https://issues.apache.org/jira/browse/GROOVY-8056
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.8
> Reporter: Andy Wilkinson
> Assignee: John Wagenleitner
> Priority: Major
> Fix For: 2.4.12
>
>
> When {{GroovyCodeSource}} is created from a {{URL}} it calls
> {{url.openConnection.getContentEncoding()}}. When it's a {{file:}} URL, this
> causes a {{FileInputStream}} to be opened and never closed. The stack trace
> for it being opened is:
> {noformat}
> at java.io.FileInputStream.<init>(Unknown Source)
> at java.io.FileInputStream.<init>(Unknown Source)
> at sun.net.www.protocol.file.FileURLConnection.connect(Unknown Source)
> at
> sun.net.www.protocol.file.FileURLConnection.initializeHeaders(Unknown Source)
> at sun.net.www.protocol.file.FileURLConnection.getHeaderField(Unknown
> Source)
> at java.net.URLConnection.getContentEncoding(Unknown Source)
> at groovy.lang.GroovyCodeSource.<init>(GroovyCodeSource.java:176)
> at
> groovy.text.markup.MarkupTemplateEngine$MarkupTemplateMaker.<init>(MarkupTemplateEngine.java:222)
> at
> groovy.text.markup.MarkupTemplateEngine.createTemplateByPath(MarkupTemplateEngine.java:145)
> {noformat}
> I believe that keeping a local reference to the {{URLConnection}} and then
> calling {{getInputStream().close()}} on it will fix the problem.
> For reference
> [this|https://github.com/spring-projects/spring-boot/issues/7892] is the
> Spring Boot issues where the problem was originally reported.
