I'm recognizing an IAE which populates the error log while typing, so this happens frequently. This occurs in my Xtext dev workspace, but I did not see this in other workspaces so far. When I have more insights I'll add details. java.lang.IllegalArgumentException: Alignment value is not an integer: null at

The error occurs while I'm typing in a class that has currently syntax issues. When the issue is resolved, the error does not happen anymore.
Incidentally, I had a somewhat similar exception recently, which happened when I tried to copy/edit a formatter profile: java.lang.IllegalArgumentException: Alignment value is not an integer: null at org.eclipse.jdt.core.formatter.DefaultCodeFormatterConstants.getWrappingStyle(DefaultCodeFormatterConstants.java:5312) at org.eclipse.jdt.internal.ui.preferences.formatter.FormatterModifyDialog$LineWrapPreference.updateWidget(FormatterModifyDialog.java:211) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$Preference.init(ModifyDialog.java:280) at org.eclipse.jdt.internal.ui.preferences.formatter.FormatterModifyDialog$LineWrapPreference.init(FormatterModifyDialog.java:205) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree.addChild(ModifyDialog.java:907) at org.eclipse.jdt.internal.ui.preferences.formatter.FormatterModifyDialog.lambda$20(FormatterModifyDialog.java:1225) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree$PrefBuilder.build(ModifyDialog.java:839) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree$PrefBuilder.build(ModifyDialog.java:1) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree$SectionBuilder.build(ModifyDialog.java:822) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree$SectionBuilder.build(ModifyDialog.java:1) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog$ProfilePreferenceTree$SectionBuilder.build(ModifyDialog.java:822) at org.eclipse.jdt.internal.ui.preferences.formatter.FormatterModifyDialog.createLineWrapTree(FormatterModifyDialog.java:1207) at org.eclipse.jdt.internal.ui.preferences.formatter.FormatterModifyDialog.createPreferenceTree(FormatterModifyDialog.java:575) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog.createMainArea(ModifyDialog.java:1262) at org.eclipse.jdt.internal.ui.preferences.formatter.ModifyDialog.createDialogArea(ModifyDialog.java:1246) I only had a brief look at the code but wondered if this could happen, if a new formatter option has been added, but some persisted state didn't yet have it? Or an incompatibility between JDT/Core and JDT/UI plugins?? Anyway, it seems that both cases originate in JDT/UI, which calls JDT/Core with an illegal null value.

Can you share contents of your .metadata\.plugins\org.eclipse.core.runtime\.settings workspace folder (mainly jdt.core and jdt.ui files)? And a sample code that you're editing?

Or an incompatibility between JDT/Core and JDT/UI plugins?? To avoid such problems, jdt.ui always uses ProfileVersioner to make sure that loaded formatter profiles are updated. Hard to tell where this could go wrong, apart from manual tempering with workspace settings files.
I'm editing, for example, class org.eclipse.xtext.resource.XtextResource from https://github.com/eclipse/xtext-core.git In this project we have checked in formatter settings. https://github.com/eclipse/xtext-core/tree/master/org.eclipse.xtext/.settings
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
