[NETBEANS-6349] Recent builds of the module responsible for java source parsing break BC to JDK 8

• Type: Bug
• Status: Closed
• Priority: Critical
• Resolution: Fixed
• Affects Version/s: 12.5, 12.6
• Fix Version/s: 13
• Component/s: editor - Parsing & Indexing

Description

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.  

Issue Links

• causes: NETBEANS-6339 Formatting and indentation options for Java in NetBeans 12.6 are broken
• causes: NETBEANS-6285 Netbeans 12.6 compiles against JDK9+ CharBuffer.flip() and no longer runs on JDK 8
• causes: NETBEANS-6281 Hitting the enter key at the end of a line of code jumps the cursor to the start of the next line, and the code is not formatted for alignment or indentation.
• causes: NETBEANS-6064 java.lang.NoSuchMethodError: java.nio.CharBuffer.flip()
• causes: NETBEANS-6182 Implement abstract methods -> java.lang.NoSuchMethodError
• causes: NETBEANS-6272 Auto-indent function or pressing tab character in java editor throws NoSuchMethodError
• causes: NETBEANS-6286 trying to indent throws java.lang.NoSuchMethodError exception
• is duplicated by: NETBEANS-6379 Editor NoSuchMethodError on JDK1.8
