> The InMemory server is failing the test suites from the CmisJS project (https://github.com/agea/CmisJS), I traced it down to a somewhat straightforward bug in ObjectService.java (in package org.apache.chemistry.opencmis.server.impl.browser), around line 494, see below:
> {code}
> String changeToken = (changeTokens != null && changeTokens.size() > i ? changeTokens.get(i) : null);
>                 if (changeToken.length() == 0) {
>                     changeToken = null;
>                 }
> {code}
> The first statement would sometimes yields a "null" value, which is then used immediately as a valid object, resulting in NullPointerException when executing the test cases. A reasonable patch would be to change the 2nd line to:
> {code}
>         if ( (changeToken!=null) && (changeToken.length()==0) ) {
> {code}
> Wondering if this makes sense to you all...
