Reformatting incorrectly concatenates decorator and decorated identifier in a generic extends clause

[RadixSeven]

Prettier-Java 1.6.1

.prettierrc

{
  "proseWrap": "always"
}

Options:

--write

Input:

import org.jetbrains.annotations.NotNull;

public class Foo<T> {
    
  public <U extends @NotNull T> void example(U u) {}
}

Output:

import org.jetbrains.annotations.NotNull;

public class Foo<T> {

  public <U extends @NotNullT> void example(U u) {}
}

Expected behavior:
Should not delete the space in @NotNull T. The deletion changes the semantics.

Workaround

import org.jetbrains.annotations.NotNull;

public class Foo<T> {

  // @formatter:off
  public <U extends @NotNull T>
  // @formatter:on
  void example(U u) {}
}
