It looks like it's being caused by the m2eclipse plugin but I am not sure. I'm using Luna 4.4.0 with m2eclipse version 1.5.0.20140606-0033. How to fix?

An internal error occurred during: "Initializing Spring UAA". org/eclipse/jdt/core/JavaModelException in Spring Tool Suite

I am new to Spring.
I have installed from the spring-tool-suite-3.1.0.RELEASE-e3.8-win32 folder which contains the below folders:
apache-maven-3.0.4

sts-3.1.0.RELEASE
vfabric-tc-server-developer-2.7.2.RELEASE
I have Eclipse Juno already installed in my system.
After the installation of the STS, when I tried to open, it gave the below error:
An internal error occurred during: "Initializing Spring UAA".

Also there was another error as below:

Broken PDT install in Eclipse Luna

I am an Android and PHP developer, so I am trying to use Eclipse for both. I have my Android development up and running, no issues (Eclipse Luna). When trying to get my PDT to work as well, I create the main and library projects, but every time I try to open a PHP file, I get the following warning:
Plug-in org.eclipse.php.ui was unable to load class org.eclipse.php.internal.ui.editor.PHPStructuredEditor.
I have looked around here and online, and although there is some info on the error, nothing seems to help. I've tried the clearPersistedState flag, I've deleted (contents on disk as well) the projects and recreated, completely uninstalled and reinstalled DLTK & PDT. Any ideas what I can do to get PDT working in Eclipse?
Thanks for any help or suggestions you can provide.
Below is the full error details and Eclipse install info.
(I wasn't able to post a screenshot with install details, here is the image)

I had to completely remove Eclipse, re download a fresh version and install all software from scratch. Now I have both Android and PDT working. I hope this problem does not come back later.

Removing Spring Project nature from eclipse fixes the problem.
Removing AspectJ Capability form project also fixes the problem.
Removing all code containing lambda expressions also fixes the problem.
Can someone help me with this?

Looks like you are using an old version of AspectJ since that problem was fixed in AspectJ 1.8.1 under https://bugs.eclipse.org/bugs/show_bug.cgi?id=435446 . The problem was due to weaving into code that contained invokedynamic instructions and try..catch blocks. Have you tried updating from the dev update site:
