-----------------------------------
Dan Kulp committed a fix into the trunk weeks ago, I just merge it back to the
CXF 2.3.x and 2.2.x branch.
> Infinite loop in FileUtils.getDefaultTempDir() when "java.io.tmpdir"
> directory is not writable
> ----------------------------------------------------------------------------------------------
>
> Key: CXF-3211
> URL: https://issues.apache.org/jira/browse/CXF-3211
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.2.6
> Reporter: Eric Citaire
> Assignee: Willem Jiang
> Fix For: 2.3.2, 2.2.13, 2.4
>
>
> FileUtils.getDefaultTempDir() can go into a infinite loop when the
> "java.io.tmpdir" system property is set to an non-writable directory.
> See issue #CXF-1924.
> May be something like this would prevent an infinite loop :
> {{s = System.getProperty("java.io.tmpdir");}}
> {{File checkExists = new File(s);}}
> {{if (!checkExists.exists() || !checkExists.isDirectory() ||
> !checkExists.canWrite()) {}}
> {{throw new RuntimeException("The directory "}}
> {{+ checkExists.getAbsolutePath()}}
> {{+ " is not a writable directory");}}
> {{}}}
> {{File f = new File(s, "cxf-tmp-" + x);}}
> {{for (int attempts=0; attempts<10; attempts++) {}}
> {{x = (int)(Math.random() * 1000000);}}
> {{f = new File(s, "cxf-tmp-" + x);}}
> {{if (f.mkdir()) break;}}
> {{}}}
