Hello everybody.
i am using Eclipse Neon with STS plugin. Sometimes i got this message when i press F3 (or ctrl+FMB):

An internal error occurred during: "Compute launch button tooltip".
org.eclipse.jdt.internal.compiler.env.NameEnvironmentAnswer.<init>([Lorg/eclipse/jdt/internal/compiler/env/ISourceType;Lorg/eclipse/jdt/internal/compiler/env/AccessRestriction;)V

Besides, if i press ctrl+shift+h and i search the class i got:
An internal error occurred during: "Computing type hierarchy of...
org.eclipse.jdt.internal.compiler.env.NameEnvironmentAnswer.<init>([Lorg/eclipse/jdt/internal/compiler/env/ISourceType;Lorg/eclipse/jdt/internal/compiler/env/AccessRestriction;)V

the most interesting behavior is that in some java classes F3 (or ctrl+FMB) works very well and others not, it is not even there is color syntax.

it is not even there is color syntax.
memory problems? java 8 problems?

Best regards.

From the top of your stack trace it seems you have AJDT installed in a version that is incompatible with JDT. Please check your configuration and/or report to the AJDT team.
