retrieved from Java element: Ljava/util/Collections$CheckedMap<TK;T,V;>; Signature retrieved from binding key for which we ask type parameters: <K:,V:>Ljava.util.Collections$CheckedMap; char[] in scanTypeSignature [<, K, :, ,, V, :, >, L, j, a, v, a, ., u, t, i, l, ., C, o, l, l, e, c, t, i, o, n, s, $, C, h, e, c, k, e, d, M, a, p, ;] start in scanTypeSignature: 3 Setting to major since this blocks type hierarchies on generic types.
Additional hint: created type hierarchy for Map from Java 5.
Cannot reproduce. For me the key is Ljava/util/Collections$CheckedMap<TK;TV;>;
Reproduced. This happens only if the binary type is not in the Java model cache.
Fixed HierarchyBinaryType#getGenericTypeSignature() to not add an extra comma between type parameters. Added regression test TypeHierarchyTests#testGeneric6()
Verified for 3.1 M7 using build I20050509-2010 + jdt.core HEAD.
