Fixed copy-paste mistake in MutableLHash
Prepared *HashCapacities and type-agnostic hash bases (MutableDHash, etc.) for maps with parallel key-value layout. Fixed bug in MutableLHash.postInsertHook() (appeared in UpdatableQHash and DHash specializatons).
Minor improvements of HashMapQueryUpdateMethodGenerator
Fixed bugs in method template usages in the lib impl and improved error detection in JPSG to prevent such mistakes in future
Fixed jvmargs declaration in gradle.properties -- was silently discarded
Improved JPSG error detection further, added checks of nonexistent dimensions in conditons, fixed a bug in impl tests due to this
LHash bulk removals (removeAll, retainAll and removeIf) and iterators with remove support were broken. Resolution led to impl-generator refactoring also
