JUnit Publishing error with invalid xml.

The JUnit Publishing used to work. But now it SOMETIMES fails due to the invalid JUnit report xml. I checked the xml file and find there is some extra >.

1. We now have 3 JBE run on a same server, but with different  build engine ID.
2. I recently make my JBE run as a Windows service. Others still run from CLI.

As I said, it doesn't always occur. Below is the log.
