I think it is certainly part of it. I also don't like Java because best practices include hiding everything inside objects and developers are generally against using simple functions. I also dislike how leaky abstractions are common in average Java code and the unnecessary verbosity. Java 8 helped with many of these yet, it is uncommon to see Java 8 syntax in most sources I work with. Many large companies just migrated or in the middle of migration to Java 8.
