It appears that JDT went ahead and implemented the spec change https://bugs.openjdk.org/browse/JDK-8231435 eagerly.
It also appears that javac never implemented this change as can be seen from this snippet

@interface Simple {}
class Test { <@Simple T> void m(T arg1) {} }

being rejected by javac 14-20 with the diagnostic

X.java:2: error: annotation @Simple not applicable in this type context
class Test { <@Simple T> void m(T arg1) {} }
              ^
1 error

Now JLS has changed course with https://bugs.openjdk.org/browse/JDK-8261610 and javac also is implementing https://bugs.openjdk.org/browse/JDK-8303784

Current reading of JLS 9.6.4.1 :

...
If an annotation of type java.lang.annotation.Target is not present on the
declaration of an annotation interface A, then A is applicable in all declaration
contexts and in no type contexts.
...
