-----------------------------------------
Summary: Recent builds of the module responsible for java source
parsing break BC to JDK 8
Key: NETBEANS-6349
URL: https://issues.apache.org/jira/browse/NETBEANS-6349
Project: NetBeans
Issue Type: Bug
Components: editor - Parsing & Indexing
Affects Versions: 12.5, 12.6
Reporter: Thomas Schapitz
There are 6 linked Issues, that all follow a common pattern, pointing to a
common cause:
* They are accompanied by an java.lang.NoSuchMethodError:
java.nio.CharBuffer.flip()Ljava/nio/CharBuffer;
* The users indicate, they are running NB 12.5+ with JDK8
* The errors occur during parsing.
Sure enough, JDK 8 hasn't
java.nio.CharBuffer.flip()Ljava/nio/{*}+CharBuffer+{*},
it has only java.nio.CharBuffer.flip()Ljava/nio/{+}*Buffer,*{+} which it
inherits from Buffer.
Which means: the Module in question has obviously been compiled against a
library more recent then JDK8, at least JDK9, which has this method.
Consequences:
This and the 6 linked issues will automatically be fixed with the rollout of NB
13, which will require JDK 11 as prerequisite anyway.
In the mean time, users may work around the problem, by immediately switching
to JDK 9+ when executing Netbeans. Note that they should still be able to
develop and build for JDKs 8 an prior.
