Unsupported option defined for thread pattern in defaults.xml CONSOLE_LOG_PATTERN

[apogrebnyak]

The file in question is https://github.com/spring-projects/spring-boot/blob/master/spring-boot/src/main/resources/org/springframework/boot/logging/logback/defaults.xml

In CONSOLE_LOG_PATTERN, the thread pattern is defined as %15.15t{14}
According to logback documentation (and code), t/thread conversion word does not support any additional options.

For clarity, can you remove it, and leave just the field formatting options in-place, as %15.15t?

basic.xml in 1.1.x has the same problem
