Description julien CLA 2015-12-04 08:31:59 EST 
Hello,

Since we use eclispe 4.x, the first opening of a jsp file is very slow : eclipse freeze at least 2 minutes.
After this fisrt opening, the others is opening in one second.
it happens with "jsp editor" or "text editor".

Our project is a big project j2EE with a lot of jsp and java classes.
We have no trace in eclipse log, no error : we don't know what eclipse do.

We use eclipse 4.5.1 64 bits, with jdk 1.8 64 bits on windows 7 64 bits.
In eclipse.ini:
-vmargs
-Xverify:none
-Xss4m
-Dosgi.requiredJavaVersion=1.7
-Xms512m
-Xmx2560m


The computer is a DELL 8GO , I7.

Thank You.

We have the same issue on each project on Eclipse : the first opening is very slow, and after it's ok.
So, even if we open a jsp on a project, in another eclipse project, we need wait the first opening of jsp.

Which log can I give You to help us  ?

Thank You.
