Description Stephane Epardaud

2015-09-02 13:02:46 EDT

I'm trying to create a new Eclipse project based on the JDK8 langtools sources (http://hg.openjdk.java.net/jdk8/jdk8/langtools/archive/tip.zip) and when I do that I get the following errors:

To reproduce: unpack, do "New > Java Project" and set the project name to the name of the folder where you unpacked this in your workspace.

Comment 1 Jay Arthanareeswaran

The error is because we are trying to create an array with more than 255 dimensions, which is not allowed per JVM spec. Try to compile the Test256a.java with Javc, which fails.

It would have been useful to mention the error as part of the IAE, though. Also, I think we shouldn't abort importing the project completely just because one CU has problems in it.

Markus, is this something that can be addressed in UI as is? Some change needed in core?

Comment 2 Stephane Epardaud

2015-09-03 11:19:32 EDT

OK, that's good news I suppose. I didn't get to the part where I had to select the source folder. I assume Eclipse autodetected the tests as a source folder. I would not have selected it myself. Is there a way to set this manually during import so I can avoid this issue?

Bulk move out of 4.8

Comment 4 Eclipse Genie

2020-05-06 12:17:51 EDT

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. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. 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.
