I tried this with a clean checkout of master on a windows box (which I don’t
normally do, but for this test…).
I’m not able to reproduce. My environment is slightly different in that I’m not
using Eclipse, but rather building on Netbeans 8.2.
I am definitely using a 64 bit Java 8 (C:\Program Files\Java\jdk1.8.0_144).
Is it possible that you have an older JDK? IIRC, Eclipse Mars was a JDK 7 based
build.

Subject: [Geotools-devel] GeoTools gt-metadata module does not build in
master...
Hi, I am trying to build GeoTools and I get two errors in gt-metadata module.
I use Eclipse - Mars.1 Release (4.5.1) - in Windows.
...\modules\library\metadata\src\main\java\org\geotools\factory\CategoryRegistry.java
1)
public CategoryRegistry(final FactoryRegistry factoryRegistry,
final Iterable<Class<?>> categories) {
...
// use an unmodifiable map to guarantee immutability
this.categories = stream(categories)
.collect(
collectingAndThen(
toMap(category -> category,
category -> new
InstanceRegistry<>(factoryRegistry,category), <-- ERROR
(firstRegistry, secondRegistry) ->
secondRegistry),
Collections::unmodifiableMap));
}
ERROR --> Type mismatch: cannot convert from Object to
Map<Class<?>,CategoryRegistry.InstanceRegistry<?>>
2)
public <S> Optional<S> getInstanceOfType(Class<S> type) {
...
return streamCategories().filter(category ->
category.isAssignableFrom(type))
.map(this::instanceRegistry)
<-- ERROR
.flatMap(registry ->
stream(registry.getInstanceOfType(type))).findFirst();
}
ERROR -> Type mismatch: cannot convert from Stream<Object> to <unknown>
I can fix these errors with a pair of minor changes:
1)
public CategoryRegistry(final FactoryRegistry factoryRegistry,
final Iterable<Class<?>> categories) {
...
// use an unmodifiable map to guarantee immutability
this.categories = stream(categories)
.collect(
collectingAndThen(
toMap(category -> category,
category -> new
InstanceRegistry<Class<?>>(factoryRegistry,category),
(firstRegistry, secondRegistry) ->
secondRegistry),
Collections::unmodifiableMap));
}
2)
public <S> Optional<S> getInstanceOfType(Class<S> type) {
...
return streamCategories().filter(category ->
category.isAssignableFrom(type))
.map(category -> (InstanceRegistry<?>)
instanceRegistry(category))
.flatMap(registry ->
stream(registry.getInstanceOfType(type))).findFirst();
}
But I do not know if they are right. Could you help me? Am I missing anything?
Thanks in advance
Alvaro
