Gmail Api Potential memory leak in com.google.api.client.util.escape.Platform #923

Closed GoogleCodeExporter closed 9 years ago

Version of google-api-java-client (e.g. 1.15.0-rc)?
From my pom, I updated to the latest version but found it initially in earlier 
versions.
<dependency>
            <groupId>com.google.apis</groupId>
            <artifactId>google-api-services-gmail</artifactId>
            <version>v1-rev18-1.19.0</version>
</dependency>

Java environment (e.g. Java 6, Android 2.3, App Engine)?
Java 7, Tomcat 7, Spring MVC

Describe the problem.
Tomcat is reporting a memory leak on shutdown:
SEVERE: The web application [/#####] created a ThreadLocal with key of type 
[com.google.api.client.util.escape.Platform$1] (value 
[com.google.api.client.util.escape.Platform$1@6daa869b]) and a value of type 
[char[]] (value [[C@566b625c]) but failed to remove it when the web application 
was stopped. Threads are going to be renewed over time to try and avoid a 
probable memory leak.

How would you expect it to be fixed?
I would like the ThreadLocal created in 
com.google.api.client.util.escape.Platform to be properly disposed of. This was 
reported as fixed in the GSON library.

But it appears to have crept back in somehow.
