Eirik Bakke commented on NETBEANS-430:
--------------------------------------
The error occurred again today when I was starting my NetBeans Platform app:
"java.lang.ClassFormatError: Absent Code attribute in method that is not native
or abstract in class file com/sieuferd/datamodel/ViewPropertyTypes$3".
This is a Maven-based NetBeans platform application with Compile-on-Save
enabled, so there are two different versions of the ViewPropertyTypes.class and
ViewPropertyTypes$3.class files: one pair in the JAR file that was built on the
last clean build (with last-modified-date March 21), and one pair in the
"common-datamodel/target/classes/com/sieuferd/datamodel" directory that were
generated by Compile-on-Save (with last-modified-date March 23).
Note that I have never edited the ViewPropertyTypes source since the last
Compile-on-Save, but Compile-on-Save has regenerated it for some reason. If I
do edit the source file, the class files are indeed regenerated with a
last-modified-date of today. The error still occurs, until the next clean build.
The pairs of class files are attached, along with the console output.

> Key: NETBEANS-430
> URL: https://issues.apache.org/jira/browse/NETBEANS-430
> Project: NetBeans
> Issue Type: Bug
> Components: guibuilder - Code, java - Classfile, java - Source,
> projects - Maven
> Affects Versions: 9.0
> Environment: Apache NetBeans IDE Dev (Build
> incubator-netbeans-release-205-on-20180202), OpenJDK 64-Bit Server VM
> 9.0.4.1+11, Mac OS X version 10.9.5
> Reporter: Eirik Bakke
> Priority: Major
> Attachments: Class Files causing Trouble.zip, parseerror.txt

>
> While editing Java sources in a maven-based multi-module NetBeans Platform
> application on NetBeans 9.0 beta, the following IDE exception happens at
> irregular intervals, while editing unrelated files in a different module:
> {noformat}
> ALL [null]: An error occurred during parsing of
> '/var/folders/38/g_r_gdts0wx49_kbz5sjfj300000gn/T/vcs-1518825448194/vcs-1519673427266/FilterPanel.java'.
> Please report a bug against java/source and attach dump file
> '/Users/ebakke/Library/Application
> Support/NetBeans/dev/var/log/FilterPanel_8.dump'.
> {noformat}
> See the attached text file for the complete log dump and stack trace (can't
> attach the ".dump" file as it contains source code). The source file in
> question, FilterPanel.java, is generated in part by the Matisse GUI builder
> (so there's also a FilterPanel.form file). I've also got maven
> Compile-on-Save enabled.
> At other times, occasionally when running the same NetBeans Platform-based
> application, the application itself throws the following exception,
> mentioning the same file:
> {noformat}
> java.lang.ClassFormatError: Absent Code attribute in method that is not
> native or abstract in class file com/somepackage/project/filter/FilterPanel$2
> {noformat}
> See again the attached text file for the complete log dump and stack trace.
