Exceptions I would love to see fixed in 5.1
Here are some ways to get IDEA to throw exceptions, some even while just
editing java code. Looking at the exception reports in the tracker they
happen quite often. By providing the information to reproduce here I'm
hoping it's possible to fix these faster.
1. Unclosed string literal with back slash
Type or copy-paste an unclosed string literal containing a back slash
anywhere in a java source file. Wait a few seconds and boom!
http://www.jetbrains.net/jira/browse/IDEADEV-2956
2. Case statement completion
Completing a case statement which is not contained in a switch. Doesn't
happen as often, but it should work.
class Completion {
void foo() {
case // press ctrl+space here
}
}
http://www.jetbrains.net/jira/browse/IDEADEV-2970
3. Inverting an if statement inside a foreach loop
If I invert an if statement which is located in a foreach loop, IDEA
takes 100% cpu for a couple of seconds and then starts spewing
exceptions. IDEA does not return to a working state if it is not restarted.
void foo(String[] strings) {
for (String string : strings) {
if (string.equals("5")) { // invert me
System.out.println("five");
}
}
}
http://www.jetbrains.net/jira/browse/IDEA-4926
http://www.jetbrains.net/jira/browse/IDEADEV-2554
4. Inspection without description
The "Unused Property" inspection doesn't have a description. Trying the
view the description throws an exception. If I leave the focus on that
inspection and close the Errors dialog, it is impossible to open it
again without first closing IDEA and manually editing a config file. Two
issues in one I think: This inspection should have a description and
inspections without a description shouldn't throw exceptions.

Hello Bas,
Thanks a lot for the hints!
1-3 fixed (first was most harmful, there was a bug in java lexer; and third
was most tough).
Ann promized to come up with 4th tomorrow.

This happens pretty soon after I've opened up a jsp file.

Hi Max,
Thank you and your team for fixing those so fast and I'm happy I could
help. It's good that 5.1 will be released without these.
Thank you again,
Bas

I got this one more or less every time i want to move a member.
So this happens very often.

I don't know how this could be reproduced.
Could you give me any hints?
I have to attest that 5.1 EAP is much, MUCH better in terms of exceptions.
JavaScript support is great, too.
We have several Java files that 5.0.x chokes on but 5.1 is happy with.
