<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I have done a rebuild [1] of Java packages using Java 8. About 20 % of<br>
packages currently fail, but mostly for reasons not related directly to<br>
Java 8.<br>
<br>
Some of problems I have found:<br>
<br>
1) Some collection iterators return elements in different order - most<br>
common problem, which breaks tests in many packages and who knows what<br>
else.<br>
<br>
Solution: work with upstream to fix buggy code that relies on order of<br>
elements in unordered collections.<br>
<br>
2) Assertion failure jn javadoc - rhbz#1082186<br>
<br>
3) Some new methods were added, which breaks existing code. Examples:<br>
java.util.Map - remove(K,V)<br>
java.util.List - sort(Comparator)<br>
java.lang.reflect.TypeVariable - getAnnotatedBounds()<br>
sun.security.jgss.spi.GSSCredentialSpi - impersonate(GSSNameSpi)<br>
<br>
Solution: patch code to implement new methods<br>
<br>
4) java.lang.reflect.Proxy - fields of proxy classes cannot be accessed<br>
using reflection any longer?<br>
<br>
<br>
[1] The rebuild was done for testing purposes only. Resulting Builds<br>
are not included in Fedora.<br>
